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 36 cardholders has a mean credit card balance of $5,313 and a standard deviation of $675. At α=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 H0 and Ha. Which of the following correctly states H0 and Ha? A. H0: μ=$5,200 Ha: μ≠$5,200 B. H0: μ>$5,200 Ha: μ≤$5,200 C. H0: μ>$5,200 Ha: μ≤$5,200 D. H0: μ≥$5,200 Ha: μ<$5,200 E. H0: μ≤$5,200 Ha: μ>$5,200 Your answer is correct. F. H0: μ=$5,200 Ha: μ>$5,200 (b) Find the critical value(s) and identify the rejection region(s). What is(are) the critical value(s), t0? t0=enter your response here (Use a comma to separate answers as needed. Round to three decimal places as needed.)

Question
A credit card company claims that the mean credit card debt for individuals is greater than
normally distributed.
$5,200.
You want to test this claim. You find that a random sample of
36
cardholders has a mean credit card balance of
$5,313
and a standard deviation of
$675.
At
α=0.10,
can you support the claim? Complete parts (a) through (e) below. Assume the population is (a) Write the claim mathematically and identify
H0
and
Ha.
Which of the following correctly states
H0
and
Ha?
H0:
μ=$5,200
Ha:
μ≠$5,200
H0:
μ>$5,200
Ha:
μ≤$5,200
H0:
μ>$5,200
Ha:
μ≤$5,200
H0:
μ≥$5,200
Ha:
μ<$5,200
H0:
μ≤$5,200
Ha:
μ>$5,200
H0:
μ=$5,200
Ha:
μ>$5,200
(b) Find the critical value(s) and identify the rejection region(s).
What is(are) the critical value(s),
t0?
t0=enter your response here
