Customer Question

This same question with different numbers JA: The Advanced Math Tutor can help you get an A on your homework or ace your next test. Tell me more about what you need help with so we can help you best. Customer: Random and independent samples of 70 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 109.1 commercials during prime time, with a standard deviation of 5.5 commercials. The second network aired a mean of 110.9 commercials, with a standard deviation of 5.5 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 , 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 complete the table belowwhat is the lower limit of the 95% confidence interval what is the upper limit of the 95% confidence interval JA: Is there anything else the Advanced Math Tutor should be aware of? Customer: interval for mu1 - mu2 JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Advanced Math Tutor about your situation and then connect you two.

Assuming that the large sample sizes mean that your course permits the use of the z-statistic in the calculation of the confidence interval, then the limits are:

Lower limit = -3.6221

Upper limit = 0.0221

If the above assumption is not correct, then the t-statistic must be used, and the limits are:

Lower limit = -3.6382

Upper limit = 0.0382
