Please answer these questions:

1. Choose the appropriate test for each of the hypotheses below (8 pts in total; 2 pts each). [Be sure to watch Ch 15 video first] Note: It is NOT sufficient to simply answer what the test is. To earn the full point, you need to explain your answer, that is, go through the 3 steps as explained in the video.

Hypothesis 1 (H1): The Stranger Things season 4 receives a higher rating compared to its season 1 or season 2. H2: More seniors than juniors take summer courses at SJSU. H3: Perceived convenience (on 7-point scales) of mobile payments will positively predict consumers' intentions (on 100-point scales) to use mobile payments. H4: Students who complete the A-L version of IPA 7 should score the same as students who complete the M-Z version of IPA 7.

2. Chi-square test (4 pts in total) The cross-tab below shows the number of consumers who ordered from Panera Bread by age group based on a survey of 95 people:

	Ordered	Did not ordered	Total
15-25 years old	22	26	48
40-50 years old	32	15	47
Total	54	41	95

A) First, calculate the expected frequency for each cell. Keep one decimal place. Show all the calculations.

	Ordered	Did not ordered	Total
15-25 years old			48
40-50 years old			47
Total	54	41	95

B) Then, calculate the chi-square statistic. Show all the calculations.

C) The critical chi-square value is 3.84 at = .05, df=1. If the null hypothesis is that consumers' age does not affect if they order from Panera Bread, and the alternative hypothesis is that consumers' age affects if they order from Panera Bread, which hypothesis is supported? And explain.

Thank you.
