A credit card company claims that the mean credit card debt for individuals is greater than $5,000. You want to test this claim. You find that a randor.
sample of 27 cardholders has a mean credit card balance of $5,226 and a standard deviation of $600. At a = 0.01, can you support the claim? Comp
parts (a) through (e) below. Assume the population is normally distributed.
(a) Write the claim mathematically and identify Ho and H.
a
Which of the following correctly states H, and H2?
O A. Ho: H2S$5,000
Ha:H< $5,000
O B. Ho H=$5,000
Ha: H> $5,000
O C. Ho = $5,000
Ha H#$5,000

O D. Ho H> $5,000
O E. Ho us $5,000
Ha > $5,000
O F. Ho H> $5,000
Ha: Hs $5,000
Ha HS $5,000
