Question

You wish to test the following claim (Ha) at a significance level of α=0.001.

      Ho:μ=56.5
      Ha:μ≠56.5

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

data
57.4
55.1
66.2
39.6
70.1
46
85.7
56.9
35.6

What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value = ± ___________

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic = ____________

The test statistic is...

A.) in the critical region

B.) not in the critical region

 

This test statistic leads to a decision to...

A.) reject the null

B.) accept the null

C.) fail to reject the null



As such, the final conclusion is that...

A.) There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 56.5.

B.) There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 56.5.

C.) The sample data support the claim that the population mean is not equal to 56.5.

D.) There is not sufficient sample evidence to support the claim that the population mean is not equal to 56.5.
