Question

A sample of 37 observations is selected from a normal population. The sample mean is 21, and the population standard deviation is 3. Conduct the following test of hypothesis using the 0.02 significance level.

 

H0: μ ≤ 20

H1: μ > 20

 

  1. Is this a one- or two-tailed test?

 

multiple choice 1

  • One-tailed test
  • Two-tailed test

 

 

  1. What is the decision rule?

 

multiple choice 2

  • Reject H0 when z > 2.054
  • Reject H0 when z ≤ 2.054

 

 

  1. What is the value of the test statistic? (Round your answer to 2 decimal places.)

 

 

 


 

 

  1. What is your decision regarding H0?

 

multiple choice 3

  • Fail to reject H0
  • Reject H0

 

 

  1. e-1. What is the p-value? (Round your answer to 4 decimal places.)

 

 

 

 

  1. e-2. Interpret the p-value? (Round your final answer to 2 decimal places.)
