Question
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 32 cardholders has a mean credit card balance of $5,242 and a standard deviation of
$575. At a = 0.01, can you support the claim? Complete parts (a) through (d) below. Assume the population is normally distributed.
(a) Write the claim mathematically and identify Ho and H2.
Which of the following correctly states H, and H,?
O A. Ho: µ> $5,100
Ha: us $5,100

Hai µ > $5,100
С. Но: 3 $5,100
Ha: u# $5,100
O D. Ho: µ2 $5,100
Ha:u< $5,100
O E. Ho: µ> $5,100
Ha: us $5,100
Ο F H0: μS $5,1 00
