Q: 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 25 19
Afternoon Shift 8 9 12 15
At the .05 significance level, can we conclude there are more defects produced on the afternoon shift?
