Question

The null and alternate hypotheses are:

 

H0 : μd ≤ 0

H1 : 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 10 12 15 18
Afternoon shift 8 9 12 17

At the 0.05 significance level, is there a difference in the mean number of citations given by the two shifts?

Required:

a. What is the p-value? Note: P-value calculators are available through online search. (Round your answer to 4 decimal places.)

b. what is your decision regarding the null hypothesis?

Reject or Do not reject

c. What is the conclusion indicated by the analysis?

Thre are more defective parts produced on?
