A poultry farm sells eggs classified as large, which requires the mean weight of the individual eggs to be 2 oz. The department of weights and measures weighs a random sample of 500 eggs to determine if the mean weight is less than 2 oz at a significance level of 0.05. The results of the sample are given below.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms.
