Question

The null and alternative 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	14	11	14	19
Afternoon shift	13	10	14	16

At the 0.01 significance level, can we conclude there are more defects produced on the Afternoon shift?

b. Compute the value of the test statistic. (Round the final answer to 3 decimal places.)

d. Determine the p-value. (Round the final answer to 4 decimal places.)

Answer 1

Let the sample of afternoon shift be 1 and day shift be 2. Then,

B.

D.

df = n-1

= 3

p-value = 0.9294
