3. A survey was conducted two years ago asking college students their top motivations for using a credit card. To determine whether this distribution has changed, you randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the claimed or expected distribution? Use a = 0.10. Complete parts (a) through (d). Response Old Survey % 27% New Survey Frequency, f Rewards Low rates Cash back Discounts Other 110 24% 98 21% 107 7% 46 21% 64 a. State H, and H, and identify the claim. What is the null hypothesis, Ho? O A. The distribution of motivations differs from the expected distribution. O B. The distribution of motivations is 27% rewards, 24% low rate, 21% cash back, 7% discounts, and 21% other. O C. The distribution of motivations is 110 rewards, 98 low rate, 107 cash back, 46discounts, and 64 other. What is the alternate hypothesis, H,? O A. The distribution of motivations differs from the…
A researcher selects a sample of 6 men and 11 women. She asks participants to rate the likelihood they would do female-stereotyped jobs (such as nursing or school teaching) on a scale from 1 = not likely at all to 5 = very likely. Men indicated that they would be less likely to do these jobs (M = 2.1) compared with women (M = 4.3). What is the weighted mean for the combined sample of 17 total participants? O O 2.1 4.3 3.2 3.5
