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.

### (a) Write the claim mathematically and identify \( H_0 \) and \( H_a \).
Which of the following correctly states \( H_0 \) and \( H_a \)?
- A. \( H_0: \mu \ge 4,800 \)
\( H_a: \mu < 4,800 \)
- B. \( H_0: \mu = 4,800 \)
\( H_a: \mu > 4,800 \)
- C. \( H_0: \mu > 4,800 \)
\( H_a: \mu \le 4,800 \)
- D. \( H_0: \mu = 4,800 \)
\( H_a: \mu \neq 4,800 \)
- **E. \( H_0: \mu \le 4,800 \)
\( H_a: \mu > 4,800 \)**
- F. \( H_0: \mu > 4,800 \)
\( H_a: \mu \le 4,800 \)

### (b) Find the critical value(s) and identify the rejection region(s).
What is(are) the critical value(s), \( t_0 \)?
- \( t_0 = \) [ ]
