1. **State the problem:** We are conducting a formal hypothesis test to determine if the mean wait time at the Space Mountain ride is equal to 49 minutes.
2. **Null hypothesis (H0):** The claim is that the mean wait time is 49 minutes, so
$$H_0: \mu = 49$$
3. **Alternative hypothesis (H1):** The alternative hypothesis tests if the mean is not equal to 49 minutes, so
$$H_1: \mu \neq 49$$
4. **Possible conclusions about the null hypothesis:**
- We **never accept** the null hypothesis; we either reject it or fail to reject it.
- We **never accept** the alternative hypothesis; we either reject it or fail to reject it.
- The correct conclusions are:
- **Reject the null hypothesis (F)** if the data provides sufficient evidence against it.
- **Fail to reject the null hypothesis (D)** if the data does not provide sufficient evidence against it.
5. **Summary of correct options:**
- Reject the null hypothesis (F)
- Fail to reject the null hypothesis (D)
Incorrect options are A, B, C, and E because we do not accept hypotheses or reject the alternative directly.
