Question
**Hypothesis Test for a Population Mean (\(\sigma\) is Known)**

You wish to test the following claim (\(H_a\)) at a significance level of \(\alpha = 0.05\).

- \(H_0: \mu = 53.7\)
- \(H_a: \mu > 53.7\)

You believe the population is normally distributed and you know the population standard deviation is \(\sigma = 10.1\). You obtain a sample mean of \(M = 57.5\) for a sample of size \(n = 63\).

**What is the test statistic for this sample?** (Report answer accurate to three decimal places.)

- test statistic = [     ]

**What is the p-value for this sample?** (Report answer accurate to three decimal places.)

- p-value = [     ]

The p-value is...

- ( ) less than (or equal to) \(\alpha\)
- ( ) greater than \(\alpha\)

This test statistic leads to a decision to...

- ( ) reject the null hypothesis
- ( ) accept the null hypothesis
- ( ) fail to reject the null hypothesis

As such, the final conclusion is that...

- ( ) There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 53.7.
- ( ) There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 53.7.
- ( ) The sample data support the claim that the population mean is greater than 53.7.
- ( ) There is not sufficient sample evidence to support the claim that the population mean is greater than 53.7.
