Question 1 W Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. A marketing director for a beverage company conducted a study to investigate people's soda preferences in two regions of the country. The director selected a random sample of 100 people from the east coast and a random sample of 100 people from the west coast to survey. The responses are summarized in the following table. East Coast West Coast Regular soda 44 37 Diet soda 39 42 No preference 17 21 Total 100 100 Do the data provide convincing statistical evidence, at the level of a = 0.05, that the preferences are different between the two regions of the country?

Question 21, Multiple choice below. 21. The financial aid director of a large college reports that 38% of the students enrolled are receiving some sort of financial aid. A researcher claims the percentage is lower and finds (from sampling) 29 out of 116 students are receiving some sort of financial aid. At alpha = 0.05, decide whether the financial aid director's report that 38% of the students are receiving some sort of financial aid holds up. For question #21 (multiple choice), choose the alternative hypothesis. For #22, fill in the space provided with your calculated value for p hat. For question #23, fill in the space provided with your calculated z-value from the information provided. For #24, answer True or False with regard to rejecting the null hypothesis.
