A credit card company claims that the mean credit card debt for individuals is greater than $4,800. You want to test this claim. You find that a random sample of 28 cardholders has a mean credit card balance of $4,980 and a standard deviation of $650. At a = 0.10, can you support the claim? Complete parts (a) through (e) below. Assume the population is normally distributed.
