You wish to test the following claim (Ha) at a significance level of α = 0.01. H0 : μ = 52.4
Ha : μ ≠ 52.4

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 31 with mean M = 55.5 and a standard deviation of SD = 15.8.

What is the test statistic for this sample?

What is the p-value for this sample?

The p-value is...
1. less than (or equal to) α
2. greater than α

This test statistic leads to a decision to...
1. reject the null
2. accept the null
3. fail to reject the null

As such, the final conclusion is that...
1. There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 52.4.
2. There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 52.4.
3. The sample data support the claim that the population mean is not equal to 52.4.
4. There is not sufficient sample evidence to support the claim that the population mean is not equal to 52.4.
