Question

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 | 12 | 12 | 16 | 19 |

Afternoon shift | 10 | 10 | 12 | 15 |

At the .05 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

4. What is your decision regarding H0?

Answer #1

1) Reject H0 if t > 2.353

2)

value of the test statistic t=5.196

3) p-value =0.0069

4) reject Ho
