![For the following information, determine whether a normal sampling distribution can be used, where \( p \) is the population proportion, \( \alpha \) is the level of significance, \( \hat{p} \) is the sample proportion, and \( n \) is the sample size. If it can be used, test the claim.
Claim: \( p > 0.44; \alpha = 0.08 \). Sample statistics: \( \hat{p} = 0.48, n = 225 \).
- The options for identifying the rejection region and test statistic are as follows:
- **B.** The rejection region is \( z > 1.41 \). (Round to two decimal places as needed)
- **C.** The rejection region is \( z < \) _____ (Round to two decimal places as needed)
- **D.** The rejection region is \( z < \) _____ or \( z > \)_____ (Round to two decimal places as needed)
- **E.** A normal sampling distribution cannot be used.
If a normal sampling distribution can be used, identify standardized test statistic \( z \). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
- **A.** \( z = \) [Answer box] (Round to two decimal places as needed)
