You believe the population is normally distributed and a standard deviation of SD=11.9SD=11.9. You obtain a sample of size n=81n=81 with mean M=72.1M=72.1.

What is the test statistic for this sample? (Report answer accurate to two 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 greater than 67.2.

There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 67.2.

The sample data support the claim that the population mean is greater than 67.2.

There is not sufficient sample evidence to support the claim that the population mean is greater than 67.2.
