A credit card company claims that the mean credit card debt for individuals is greater than $5,200. You want to test this claim. You find that a random sample of 34 cardholders has a mean credit card balance of $5,414 and a standard deviation of $675. At a =0.10, can you support the claim? Complete parts (a) through (e) below. Assume the population is normally distributed. (a) Write the claim mathematically and identify Ho and H Which of the following correctly states Ho and H,? O A. Ho: u> $5,200 H, us$5,200 O B. Ho: u= $5,200 H $5,200 C. Hạ: us $5,200 H u> $5,200 O D. Ho: u2 $5,200 Hu< $5,200 OE Ho: $5,200 Hu> $5,200 OF Ho: u> $5,200 Hus$5,200 (b) Find the critical value(s) and identify the rejection region(s). What is(are) the critical value(s), to? (Use a comma to separate answers as needed. Round to three decimal places as needed.)
