Yоu wоrk fоr а compаny thаt is having issues where many employees use passwords that are too weak. Your task is to help by writing a program that reads a list of employee passwords from a file and checks how strong they are. The program will: - read passwords from a text file (you can assume the input passwords.txt file is not erroneous) - use a function to check if a password conforms to the official company rules - write an analysis.txt back to disk with the password and whether or not it was OK Use only the features we've covered in this course: from the first 7 chapters. Use exception handling for file input / output by including a try - except block. You can check for more than one exception if you wish, but a generic Exception check should be made at a minimum. Functions to be coded in addition to a main() function: Tip: Don't try to do all these at once, I suggest getting the contents of the passwords.txt read in first, then print it to confirm you can access each password. Then, move ahead with the other tasks. 1. read_passwords() - takes a file name string and returns a list of string; you'll need to connect to the file name passed, read the list in line by line and return the list (each line holds one employee password). 2. satisfies_policy() - takes a password string, pword, and returns a true if pass has the following characteristics; false otherwise. If you can't remember how to do one of these checks do the ones you know how to do. a) pword must be a length of at least 8 b) pword must contain exactly three $ or three # characters c) pword must contain at least 1 number 3. write_report() - takes a output_file_name string a list of passwords and returns nothing; the function should create a file connection via open() to the output_file_name, iterate over each line of the file (each line will be a password), then you'll call your satisfies_policy() function on that password to determine if it's strong enough or not. - If the password is OK, you'll write to the file the password followed by the string "(OK)" - If the password is not OK as determined by your satisfies_policy() function, then you'll write to the file the password followed by an "(X)" -- meaning it violates company policy; see below for a model output examples. Don't forget that you'll need to put a new line escape character of "n" (without the quotes) after each line that you write to the file. Here's pseudocode for the main() function: main: call the read_passwords("passwords.txt") function (save the list of passwords read_passwords() returns into a variable) call the write_report("analysis.txt", list-of-read-passwords saved from the above call) When done, the analysis.txt file will contain each password and its status, such as the following where (X) is a bad password and (OK) is a good password: WeakPass (X) WeakPass1## (X) Strong$Pass1## (OK) short1## (X) NoDigits### (X) 1234567$$$ (OK) abc123$$$ (OK) Pa$$$w0rd (OK) Cash###123 (OK) mix#of$chars#9 (OK) #####999 (OK) lettersONLY (X) ###7$abc (OK) You should create passwords.txt (the input file for this assignment) using the below list. Simply copy / paste this list into passwords.txt and then access it using your read_passwords() function.

An engineer believes thаt the number оf defects оn а prоduct he is working on hаs the Poisson pmf. He collects a sample of 25 and notes the number of defects on each product. The sorted data are 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4. Perform a Chi-Square Goodness of Fit test on these data. Take all intermediate computations to four decimal places. What is the numerical value of the test statistic? Express your answer to three decimal places.
