You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size ( n=26 ) with mean ( M=51.8 ) and a standard deviation of ( S D=16.2 ).

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) ( alpha )
greater than ( alpha )

This p-value 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 64.5.
There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 64.5 .
The sample data support the claim that the population mean is less than 64.5.
There is not sufficient sample evidence to support the claim that the population mean is less than 64.5.

You wish to test the following claim ( ( Ha ) ) at a significance level of ( alpha=0.005 ).
