Question

The null and alternate hypotheses are:

H₀ : μ_d ≤ 0

H₁ : 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	11	12	14	18
Afternoon shift	9	10	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.)

Value of the test statistic

3.	What is the p-value?
