Question

You wish to test the following claim (HaHa) at a significance
level of α=0.01α=0.01.

Ho:μ=68.7Ho:μ=68.7

Ha:μ<68.7Ha:μ<68.7

You believe the population is normally distributed and you know the
standard deviation is σ=5.5σ=5.5. You obtain a sample mean of
M=67.3M=67.3 for a sample of size n=18n=18.

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 less than 68.7.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 68.7.
- The sample data support the claim that the population mean is less than 68.7.
- There is not sufficient sample evidence to support the claim that the population mean is less than 68.7.
