New Survey A survey was conducted two years ago asking college students their top motivations for using a credit Response Old Survey % Frequency, f 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 Rewards 28% 111 Low rates 23% 97 in the distribution? Use a = 0.025. Complete parts (a) through (d). Cash back 21% 109 Discounts 8% 47 Other 20% 61 a. State Ho and Ha and identify the claim. What is the null hypothesis, Ho? O A. The distribution of motivations is 28% rewards, 23% low rate, 21% cash back, 8% discounts, and 20% other. B. The distribution of motivations differs from the old survey. O C. The distribution of motivations is 111 rewards, 97 low rate, 109 cash back, 47 discounts, and 61 other. What is the alternate hypothesis, Ha? A. The distribution of motivations is 111 rewards, 97 low rate, 109 cash back, 47 discounts, and 61 other. O B. The distribution of motivations differs from the old survey. O C. The distribution of motivations is 28% rewards, 23% low rate, 21% cash back, 8% discounts, and 20% other. Which hypothesis is the claim? O Ho Ha (b) Determine the critical value, Xo , and the rejection region. Xo = (Round to three decimal places as needed.) Choose the correct rejection region below. OA. XSXO OB. X XO OD. X >XO (c) Calculate the test statistic. x' = [(Round to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim. Ho. At the 2.5% significance level, there enough evidence to conclude that the distribution of motivations the old survey
