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

      Ho:μ=64.7Ho:μ=64.7 
      Ha:μ≠64.7Ha:μ≠64.7

You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data:

data
79.7
132.8
98.2
103.6
96.2



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... which one is it (multiple choice) 

  • less than (or equal to) αα
  • greater than αα



This test statistic leads to a decision to... which one (multiple choice)

  • reject the null
  • accept the null
  • fail to reject the null



As such, the final conclusion is that... (multiple choice) 

  • There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 64.7.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 64.7.
  • The sample data support the claim that the population mean is not equal to 64.7.
  • There is not sufficient sample evidence to support the claim that the population mean is not equal to 64.7.
