Random and independent samples of 85 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 110.6 commercials during prime time, with a standard deviation of 4.8 commercials. The second network aired a mean of 109.4 commercials, with a standard deviation of 4.5 commercials. As the sample sizes are quite large, the population standard deviations can be estimated using the sample standard deviations. Construct a 90% confidence interval for J -), the difference between the mean number of commercials , aired during prime time by the first network and the mean number of commercials , aired during prime time by the second network. Then find the lower limit and upper limit of the 90% confidence interval. 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.) Lower limit: X ? Upper limit
