The null and alternative hypotheses are:

H0:μd≤0H0:μd≤0

H1:μd>0H1:μd>0

The following sample information shows the number of defective units produced on the day shift and the afternoon shift for a sample of four days last month.

Day
1 2 3 4
  Day shift 13 12 13 17
  Afternoon shift 11 9 12 15

At the 0.10 significance level, can we conclude there are more defects produced on the Afternoon shift?

a. State the decision rule. (Round the final answer to 3 decimal places.)

H0 is  (Click to select)  rejected  not rejected  if t >  .

b. Compute the value of the test statistic. (Round the final answer to 3 decimal places.)

Test statistic

c. What is your decision regarding the null hypothesis?

H0 should  (Click to select)  be rejected  not be rejected  .

d. Determine the p-value. (Round the final answer to 4 decimal places.)

The p-value is  .
