A data set includes data from student evaluations of courses. The summary statistics are n = 90, x=4.19, s= 0.61. Use a 0.05 significance level to test the claim that the population of student evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? Test Statistic? P-Value? Reject H0 if the P-value is less than or equal to the significance level a. Fail to reject H0, if the P-value is greater than a.

Question
A data set includes data from student evaluations of courses. The summary statistics are n = 90, x=4.19, s= 0.61. Use a 0.05 significance level to test the claim that the population of student evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
What are the null and alternative hypotheses?
Test Statistic?
P-Value?
Reject H0 if the P-value is less than or equal to the significance level a. Fail to reject H0, if the P-value is greater than a.
Transcribed Image Text:**Question: What are the null and alternative hypotheses?**
- **Option A:**
- \( H_0: \mu = 4.25 \)
- \( H_1: \mu > 4.25 \)
- **Option B:**
- \( H_0: \mu = 4.25 \)
- \( H_1: \mu < 4.25 \)
- **Option C:**
- \( H_0: \mu \neq 4.25 \)
- \( H_1: \mu = 4.25 \)
- **Option D:**
- \( H_0: \mu = 4.25 \)
- \( H_1: \mu \neq 4.25 \)
