The null and alternate hypotheses are:
H_{0} : μ_{d} ≤ 0
H_{1} : μ_{d} > 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 | 13 | 18 |
Afternoon shift | 8 | 9 | 12 | 16 |
At the 0.100 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.
