Question

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

      Ho:μ=76.6Ho:μ=76.6
      Ha:μ>76.6Ha:μ>76.6

You believe the population is normally distributed and a standard deviation of SD=18.2SD=18.2. You obtain a sample of size n=25n=25 with mean M=85M=85.

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 76.6.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 76.6.
  • The sample data support the claim that the population mean is greater than 76.6.
  • There is not sufficient sample evidence to support the claim that the population mean is greater than 76.6.
