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.

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 Ha-
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
Hu#$5,200
C. Hạ: us $5,200
Hu> $5,200
O D. Ho: u2 $5,200
Hu< $5,200
O E. Ho: $5,200
Hu> $5,200
OF. Ho: > $5,200
Hi uS$5,200
(b) Find the critical value(s) and identify the rejection region(s).
What is(are) the critical value(s), to?
