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 11     12     14    18   
  Afternoon shift 9     10     13    16   

At the .005 significance level, can we conclude there are more defects produced on the day shift?

1. State the decision rule. (Round your answer to 2 decimal places.)
  Reject H0 if t >     
2. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
  Value of the test statistic   
3. What is the p-value?
  p-value (Click to select)  between 0.005 and 0.05  between 0.05 and 0.1  between 0.0005 and 0.005
4. What is your decision regarding H0?
(Click to select)  Reject  Do not reject  H0
