## Question 3
You wish to test the following claim \((H_a)\) at a significance level of \(\alpha = 0.002\).
\(H_0: \mu = 68.5\)
\(H_a: \mu > 68.5\)
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size \(n = 15\) with mean \(\bar{x} = 73.1\) and a standard deviation of \(s = 6.1\).
a. What is the test statistic for this sample?
- **Test Statistic =** \_\_\_\_\_\_ (Round to 3 decimal places)
b. What is the p-value for this sample?
- **P-value =** \_\_\_\_\_\_ (Use Technology) (Round to 4 decimal places)
c. The p-value is...
- \(\circ\) less than (or equal to) \(\alpha\)
- \(\circ\) greater than \(\alpha\)
d. This test statistic leads to a decision to...
- \(\circ\) reject the null
- \(\circ\) accept the null
- \(\circ\) fail to reject the null
