Consider the table below that shows how many students from each year are in each of the Hogwart’s houses. Use this information to answer the probability question that follows.  Hint: I would recommend finding the totals for each row and column first.  Probability Table Year 1 Year 2 Year 3 Year 4 Year 5 Year 6 Year 7 Ravenclaw 30 38 34 33 39 31 35 Hufflepuff 36 33 29 37 39 35 34 Gryffindor 32 36 41 32 33 35 35 Slytherin 34 32 36 39 33 32 31   Find the probability that a randomly selected student is in year 2 or from Hufflepuff.    Make sure to type in your answer as a decimal rounded to 3 decimal places. For example, if you thought the answer was , then you would type in 0.431.

A recent study was conducted and it found that IQ’s are normally distributed with a mean of 100 and a standard deviation of 15. Use this information to find the following probability.  What is the probability that a randomly selected individual would have an IQ between 87 and 109?   Make sure to write your answer as a decimal rounded to 3 decimal places. For example, if you thought the answer was 23.173% then you would type in 0.232.

A local community college was interested in gauging how interested their students were in building a parking garage on campus. However, they knew that a large number of their students primarily took online courses, so they wanted to ensure that they compared the responses between students taking in-person classes and online classes. They decided to randomly survey 100 students taking in-person classes and 150 students taking online classes. They asked them whether or not they were interested in a parking garage being built on campus. Out of 100 students taking in-person classes, 64 of them stated they were interested. Out of the 150 students taking online classes, 91 mentioned they were interested.  Use this information to carry out the appropriate hypothesis test at the

Find the area of the surface generated when the given curve is revolved about the x-axis.  y =   on  

Use Spanish accents where appropriate. Hold the Alt key, type the numeric code, and then release the Alt key. Use the numeric keypad on the right side of the keyboard and make sure that the Num Lock is on. Alt Codes á = Alt + 0225 Á = Alt + 0193 é = Alt + 0233 É = Alt + 0201 í = Alt + 0237 Í = Alt + 0205 ó = Alt + 0243 Ó = Alt + 0211 ú = Alt + 0250 Ú = Alt + 0218 ñ = Alt + 0241 Ñ = Alt + 0209 ü = Alt + 0252 Ü = Alt + 0220 ¡ = Alt + 0161 ¿ = Alt + 0191 MAC Hold the key down longer than usual and a pop-up menu will appear. Click on the correct symbol to enter the accented character. For example, holding “a” will make “á” an option you can choose. Option Codes Accented (´) vowels = Option + e, then vowel ñ = Option + n, then n ü = Option + u, then u ¡ = Option + 1 ¿ = Option + Shift, then ?
