The null and alternate hypotheses are: Ho HdsO 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 Day shift Afternoon shift 89 12 17 10 12 15 18 At the 0.025 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. a. State the decision rule. (Round your answer to 2 decimal places.) Reject HO if t> b. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
