Question

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

      Ho:μ=77.6Ho:μ=77.6
      Ha:μ>77.6Ha:μ>77.6

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=11n=11 with mean M=89.6M=89.6 and a standard deviation of SD=10.8SD=10.8.

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 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 greater than 77.6.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 77.6.
• The sample data support the claim that the population mean is greater than 77.6.
• There is not sufficient sample evidence to support the claim that the population mean is greater than 77.6.
