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 change in the distribution? Use a = 0.10. Complete parts (a) through (d).

a. State Ho and H, and identify the claim.
What is the null hypothesis, Ho?
A. The distribution of motivations differs from the old survey.
B. The distribution of motivations is 111 rewards, 98 low rate, 108 cash back, 47 discounts, and 61 other.
O c. The distribution of motivations is 28% rewards, 23% low rate, 21% cash back, 9% discounts, and 19% other.
What is the alternate hypothesis, Ha?
