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) αα
- greater than αα
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 not equal to 66.7. - There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 66.7.
- The sample data support the claim that the population mean is not equal to 66.7.
- There is not sufficient sample evidence to support the claim that the population mean is not equal to 66.7.
