A credit card company claims that the mean credit card debt for individuals is greater than $4,900. You want to test this claim. You find that a random sample of 36 cardholders has a mean credit card balance of $5,053 and a standard deviation of $600. 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 H₂? OA. Ho: ≥$4,900 Ha μ<$4,900 OD. Ho: H>$4,900 Ha: μ≤ $4,900 B. Ho: μ≤ $4,900 Ha μ> $4,900 OC. Ho μ>$4,900 Ha: μ≤ $4,900 OE. Ho: μ=$4,900 Нa: μ> $4,900 OF.
