Random and independent samples of 65 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 108.8 commercials during prime time, with a standard deviation of 5.2 commercials. The second network aired a mean of 111.2 commercials, with a standard deviation of 5.1 commercials. As the sample sizes are quite large, the population standard deviations can be estimated using the sample standard deviations. Construct a 99% confidence interval for μ1 - μ2, the difference between the mean number of commercials μ1 aired during prime time by the first network and the mean number of commercials μ2 aired during prime time by the second network. Then complete the table below

Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.)

What is the lower limit of the 99% confidence interval?

What is the upper limit of the 99% confidence interval?
