I've got a couple questions pertaining to scenarios involving this question: Construct 90% confidence intervals for the true average wait time for customers at both the Hialeah and Miami Gardens offices. Analyze the results and indicate which office is better in terms of average customer wait time. The resulting intervals are found with a t score Hialeah: (20.947, 25.053) Miami: (17.092, 22.908) The professor said: "The CI overlaps so it cannot be said that one office better than the other"...

A: If 550 confidence intervals, each having a level of confidence of 96%, were computed for a population mean μ, approximately how many of the intervals would be expected to contain μ? (Round your answer to the nearest integer.) B: If 310 confidence intervals, each having a 95% level of confidence, were computed for a population mean μ, about how many of the intervals can be expected to contain μ? (Your answer will be an integer, of course.)

Is there a relationship between confidence intervals and two-tailed hypothesis tests? Let c be the level of confidence used to construct a confidence interval from sample data. Let α be the level of significance for a two-tailed hypothesis test. The following statement applies to hypothesis tests of the mean. For a two-tailed hypothesis test with level of significance α and null hypothesis H0: μ = k, we reject H0 whenever k falls outside the c = 1 − α confidence...
