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.
1 2 3 4
Day shift 10 12 13 18
Afternoon shift 9 10 14 15
At the 0.050 significance level, can we conclude there are more defects produced on the day shift? Hint: For the calculations, assume the day shift as the first sample.
State the decision rule. (Round your answer to 2 decimal places.)
Compute the value of the test statistic. (Round your answer to 3 decimal places.)
What is the p-value?
Between 0.10 and 0.15
Between 0.001 and 0.005
Between 0.005 and 0.01
What is your decision regarding H0?
Do not reject H0
