Question: Two large production runs have recently been completed one on the night shift and one on the day shift. The shop foreman takes a random

Two large production runs have recently been completed— one on the night shift and one on the day shift. The shop foreman takes a random sample of 100 units from each run and tests them to estimate the difference in the proportion of units in the two runs that need to be reworked. The sample from the night shift produced eight such units and the sample from the day shift produced five such units. You build a confidence interval with a margin of error of .05. What level of confidence could you associate with this interval?
