The null and alternate hypotheses are: H0:μ≤0
H1:μ>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 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.
