Exercise 13

A truth in labeling regulation states that no more than 1% of units may vary by more than 2% from the weight stated on the label. The label of a product states that units weigh 10 oz. each. A sample of 20 units yielded the following:

10.01 9.92 9.82 10.04

10.04 10.06 9.97 9.94

9.97 9.86 10.02 10.14

9.97 9.97 9.97 10.05

10.19 10.10 9.95 10.00

At α = 0:05 can we conclude that these units satisfy the regulation?
