Activity Z has estimates a = 5, b = 12, m = 7; activity X has estimates a = 5, b = 11, m = 6; and activity Y has estimates a = 3, b = 11, m = 8. Which of the following statements is BEST?

This is a by-hand hypothesis test.  You’ll need to mark this problem as number 3 on your work sheet and show the work indicated below. Situation:  An online retailer has had a consistent mean purchase price of $36 for people shopping online. They wanted to try a new pricing structure to promote buying packages of multiple items.  Before launching this new structure for everyone, they tested it on a randomly selected sample of 45 shoppers.  For the people in the sample, the mean purchase amount was $49 with a standard deviation of $15.  Complete the steps below to perform a hypothesis test at the 1% significance level to see if there is enough evidence to conclude the new pricing structure will result in a higher population mean purchase amount.  a) Write the hypotheses (you can skip that part on the online test, but on your work sheet write the hypotheses symbolically using correct notation) b) Show the work in calculating the test statistic on your work sheet.  Include the formula used and values you plugged in.  Give the answer truncated at the third decimal digit as I did in my examples.  On the online test, just indicate what the value of the test statistic is (be sure to identify it as a Z or a t value) c) Use a theoretical distribution on stat key to get the p-value.  Just note the p-value online, but include a supporting sketch on your work sheet. d) Write your conclusion online, in context. 

Test scores on a foreign language placement exam for a college are approximately normal with a mean of 245 and a standard deviation of 35.  Using stat key as we did in class, answer the following questions.  Here you can just give your answers to the number of decimal places stat key shows.  On your work sheet, number this problem 6 and include the sketches to support your answers. Both here and on your sheet, write all the digits stat key displays.  1)  What proportion of the students score below 200 on this exam? 2) What is the 75th percentile for exam scores? 3) If the college exempts students who score in the top 5% of scores, what score marks the cutoff to be exempt?
