ABC Cоmpаny prоcesses sugаr beets in bаtches that it purchases frоm farmers for $72 a batch. A batch of sugar beets costs $11 to crush in the company's plant. Two intermediate products, beet fiber and beet juice, emerge from the crushing process. The beet fiber can be sold as is for $27 or processed further for $12 to make the end product industrial fiber that is sold for $40. The beet juice can be sold as is for $43 or processed further for $28 to make the end product refined sugar that is sold for $100. Which of the intermediate products should be processed further (PLEASE SHOW YOUR WORK BY USING THE HONORLOCK ON-SCREEN CALCULATOR)?

For example, the first 3 digits of number 872683654 are 872. The number can have any number of digits but it will have atleast 3 digits. DO NOT treat the number as a string and do not use any other string/vector functions. num = input('Enter a positive number: ');
8. In а mаnuаl оn hоw tо have a number one song, it is stated that a song must be no longer than 210 seconds. A simple random sample of 40 current hit songs results in a mean length of 219.1 seconds and a standard deviation of 57.17 seconds. Use a 0.05 significance level to test the claim that the sample is from a population of songs with a mean greater than 210 seconds. Assume that this is a simple random sample selected from a normally distributed population. Show and label all seven steps. {15 pts.}

Fоr this prоblem, yоu will be writing а clаss nаmed MySortedList that provides an implementation of the interface below. Make sure that you are not using any raw types (i.e. you must use the generic type parameter in your solution). You do not need to include any import statements in your response. And, of course, assume the interface below compiles. public interface SortedList extends Iterable { int size(); void clear(); int findInsertionIndex(T element); void insert(int index, T element) throws IndexOutOfBoundsException, IllegalArgumentException; void insert(T element) throws IllegalArgumentException; int findFirstOccurrenceIndex(T element); T remove(int index) throws IndexOutOfBoundsException; T remove(T element) throws IllegalArgumentException, NoSuchElementException;} It's recommended that you read ALL of the following requirements before implementing (there are HINTS). It's strongly recommended that you implement the methods in the order in which they are detailed below to maximize code reuse and make the best use of your time. The MySortedList class must have ONE private array that is used to store the elements of the list. IMPORTANT: Duplicate elements are allowed in this SortedList. You can choose where to insert the duplicate element as long as it is contiguous (i.e. grouped with) with the other duplicates already present in the list. This class must also have a single, no-argument constructor that creates the generic array of type T with an initial length of 10. NOTE: For ease of implementation, you can assume that new T[length] is valid syntax for creating a new array of type T. You can earn 5 bonus points if you know the correct way to create a new array of a generic type that will compile in Java. The MySortedList class should also have a nested inner class named MySortedListIterator that satisfies the requirements of the Iterator interface. The iterator should iterate over the elements in the list in ascending (i,e, least-to-greatest) order. Remember that nested inner classes have access to the private data members of the enclosing class! (i.e. the iterator will be able to access the backing array and any other fields the sorted list class has) Think carefully about what state information an iterator will need to iterate over an array and don't overcomplicate it. Don't forget that one of the Iterator methods should throw a NoSuchElementException when the iterator is asked to return an element that doesn't exist! The message should tell the user that the sorted list contains no more elements. Descriptions of the behaviors for the SortedList methods are detailed below. int size() returns number of elements currently in the sorted list HINT: the size of the sorted list isn't the same as the length of the backing array. You'll want to keep track of the logical size of the collection using a private field. void clear() Empties the sorted list of all elements. All elements of the backing array should be reset to null The size of the sorted list should be reset to zero int findInsertionIndex(T element) Finds and returns the integer index where the element can be inserted while keeping the list in sorted order. The sorted order must be ascending (i.e. least-to-greatest). REMEMBER: parameterized type T is bounded to guarantee that the elements implement the compareTo(T) method. When comparing, remember that foo.compareTo(bar) will return: a negative result when foo should be placed before bar a positive result when foo should be placed after bar a result of zero when foo and bar are equal HINT: it's strongly recommended this method is implemented before ALL insert and remove methods void insert(int index, T element) throws IndexOutOfBoundsException, IllegalArgumentException Inserts an element at the specified position in the sorted list, where index 0 represents the first position in the sorted list. Remaining elements should be shifted towards the end of the sorted list (see diagram). If the underlying array is full when an element is inserted into the sorted list at a valid index, it must first be increased in size using the following method which you can assume exists: MyArrayUtils.doubleLength(T[] arr); // returns a T[] that is a deep copy of the T[] arr that is passed in. The returned array will have double the length of the array passed in. method throws IndexOutOfBoundsException when the index is invalid. The message should contain text describing the specific reason the index is invalid. An index is invalid if: the value of the index is negative the value of the index exceeds the size of the sorted list. NOTE: an index that points to the next immediately available slot is VALID (i.e. inserting at an index equal to the size is a valid operation) You may assume that IndexOutOfBoundsException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. method throws an IllegalArgumentException when the reference passed in for the element is null. The message should contain text describing the reason the argument is illegal. You may assume that IllegalArgumentException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. HINT: it's strongly recommended this method is implemented before the insert(T element) method void insert(T element) throws IllegalArgumentException Inserts an element at the end of the sorted list. This method MUST use the insert(int, T) method to perform the insertion! HINT: the implementation of this method is nearly trivial if you've implemented the findInsertionIndex(T) and insert(int, T) methods! method has the same requirements as the insert(int, T) method int findFirstOccurrenceIndex(T element) Finds and returns the integer index of the first occurrence of an element in the sorted list that is equal to the element passed in. REMEMBER: parameterized type T is bounded to guarantee that the elements implement the compareTo(T) method. When comparing, remember that foo.compareTo(bar) will return a result of zero when foo and bar are equal HINT: it's strongly recommended this method is implemented before ALL insert and remove methods T remove(int index) throws IndexOutOfBoundsException Removes and returns the element at the specified position in the sorted list, where index 0 represents the first element to be removed. Remaining elements should be shifted towards the beginning of the sorted list (see diagram). method throws IndexOutOfBoundsException when the index is invalid. The message should contain text describing the specific reason the index is invalid. An index is invalid if: the value of the index is negative the value of the index does not point to an element that exists within the sorted list. NOTE: an index that points to the last element is VALID You may assume that IndexOutOfBoundsException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. HINT: it's strongly recommended this method is implemented before the remove(T element) method. T remove(T element) throws IllegalArgumentException, NoSuchElementException Removes and returns the first occurrence of an element in the sorted list that is equal to the element passed in. Remaining elements should be shifted towards the beginning of the sorted list (see diagram). This method MUST use the remove(int index) method to perform the removal! HINT: the implementation of this method is simple if you've implemented the findFirstOccurrenceIndex(T element) and remove(int index) methods. Think about how you can use these two methods to find and remove the first occurrence of an element that is equal to the argument (and throw the required exceptions, if necessary). method throws IllegalArgumentException when the argument is null. The message should contain text describing the reason the argument is illegal. You may assume that IllegalArgumentException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. method throws NoSuchElementException when an element equal to the argument doesn't exist within the list. You may assume that NoSuchElementException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. IMPORTANT: DON'T FORGET TO IMPLEMENT THE METHOD(S) REQUIRED BY THE Iterable INTERFACE! Make sure to select the 'Preformatted' style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM. USE THE SPACE BAR INSTEAD. Tentative estimated breakdown of the points for this question is as follows: ITEM POINTS size & clear methods 10% insert methods 30% remove methods 30% MySortedList class (misc.) 10% MySortedListIterator class (misc.) 20%
