There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 58.7. There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 58.7. The sample data support the claim that the population mean is greater than 58.7. There is not sufficient sample evidence to support the claim that the population mean is greater than 58.7.

You believe the population is
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 four decimal places.)
p-value =
The p-value is...
- less than (or equal to) α
- greater than α
This test statistic leads to a decision to...
- reject the null
- accept the null
- fail to reject the null
As such, the final conclusion is that...
- There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 58.7.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 58.7.
- The sample data support the claim that the population mean is greater than 58.7.
- There is not sufficient sample evidence to support the claim that the population mean is greater than 58.7.
Given,
Sample size = 12
Sample mean = 61.2
Sample standard deviation = 7.8
Set up the null and the alternative hypothesis.
