Please calculate the test statistic
A survey was conducted two years ago asking college students their top motivations for using a credit card. You think 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 distribution? Use α = 0.05. Complete parts (a) through (d). OC. The distribution of motivations is 112 rewards, 98 low rate, 108 cash back, 48 discounts, and 59 other. What is the alternate hypothesis, H₂? OA. The distribution of motivations is 112 rewards, 98 low rate, 108 cash back, 48 discounts, and 59 other. OB. The distribution of motivations is 29% rewards, 23% low rate, 22% cash back, 7% discounts, and 19% other. c. The distribution of motivations differs from the old survey.
