Question

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

      Ho:μ=62.4Ho:μ=62.4
      Ha:μ≠62.4Ha:μ≠62.4

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

96.1 73.2 51.7 48.8 90.5
58 72.3 81.4 72.7 86.4
84.6 66.2 68 83 78.1
89.7 60.3 70.2 104.2 100.2
36.6 83.5 41.8 43.6 83
77.6 86.4 75.4 46.5 98.6
74.5 79 62.9 39.5 70.2
68.4 72.7 94.9 74.5 85.2
56.1 68.9 79 57.4 72.7



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 not equal to 62.4.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 62.4.
  • The sample data support the claim that the population mean is not equal to 62.4.
  • There is not sufficient sample evidence to support the claim that the population mean is not equal to 62.4.
