Random and independent samples of 90 recent prime time airings from each of two major networks have been considered. The first network aired a mean o 109.2 commercials during prime time, with a standard deviation of 5.1 commercials. The second network aired a mean of 110.8 commercials, with a standar deviation of 5.7 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 H₁-H2, the difference between the mean number of commercials μ, aired during prime time by the first network and the mean number of commercials ₂ 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: Upper limit: X

Question
Random and independent samples of 90 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 109.2 commercials during prime time, with a standard deviation of 5.1 commercials. The second network aired a mean of 110.8 commercials, with a standard deviation of 5.7 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 μ₁-₂, the difference between the mean number of commercials μ₁ aired during prime time by the first network and the mean number of commercials ₂ 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.
