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.
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.)
Let the sample of afternoon shift be 1 and day shift be 2. Then,
df = n-1
p-value = 0.9294
