Random and independent samples of 80 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 110.7 commercials during prime time, with a standard deviation of 4.9 commercials. The second network aired a mean of 109.3 commercials, with a standard deviation of 4.6 commercials. As the sample sizes are quite large, the population standard deviations can be estimated using the sample standard deviations. Construct a 95% confidence interval for u, -, the difference between the mean number of commercials u, aired during prime time by the first network and the mean number of commercials u, aired during prime time by the second network. Then find the lower limit and upper limit of the 95% 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: |I Upper limit: n

Question
Random and independent samples of 80 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 110.7 commercials during prime time, with a standard deviation of 4.9 commercials. The second network aired a mean of 109.3 commercials, with a standard deviation of 4.6 commercials. As the sample sizes are quite large, the population standard deviations can be estimated using the sample standard deviations. Construct a 95% confidence interval for u,-u,, the difference between the mean number of commercials u, aired during prime time by the first network and the mean number of commercials u, aired during prime time by the second network. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places.
