A credit card company claims that the mean credit card debt for individuals is greater than $5,100. You want to test this claim. You find that a random sample of 34 cardholders has a mean credit card balance of $5,255 and a standard deviation of $625. At a= 0.05, 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,? A. Ho: Hs $5,100 O B. Ho: H= $5,100 O C. Ho: u2 $5,100 Ha:u< $5,100 Hai H> $5,100 Ha: > $5,100 O D. Ho: H= $5,100 Ha: Ht $5,100 O E. Ho: H> $5,100 OF. Ho: u> $5,100 Haius $5,100 Hai Hs $5,100 (b) Find the critical value(s) and identify the rejection region(s). What is(are) the critical value(s), to? to =D (Use a comma to separate answers as needed. Round to three decimal places as needed.)

Which of the following correctly states Ho and H,?
A. Ho: HS $5,100
O B. Ho: H= $5,100
O C. Ho: u2 $5,100
H,:u< $5,100
Hai H> $5,100
Ha: H> $5,100
O D. Ho: H= $5,100
Ha: H# $5,100
OF. Ho:> $5,100
Haiis $5,100
O E. Ho:H> $5,100
Hai HS $5,100
(b) Find the critical value(s) and identify the rejection region(s).
What is(are) the critical value(s), to?
