Use the technology of your choice to obtain the required Tukey multiple-comparison confidence intervals with a family confidence level of 0.95. Book Prices. The R.R. Bowker Company collects data on retail prices of books and periodicals. Information about book prices is published in Publishers Weekly and in Bowker Annual: Library and Book Trade Almanac. Independent random samples were taken to compare retail book prices for five subjects (art, law, medicine, science, and technology) and three years (1985, 1990, and 1995).  Obtained for a two-way ANOVA on these data and also supplies a table of cell and marginal means.

According to recent data by the American Marketing​ Association, 76.5​%of people in the​ 18-24 age group used social media in 2017. You want to find out what the social media proportion is among your classmates who are all between 18 and 24 years old. Suppose you obtain a random sample of 229 students and find that 202 students in this sample are active social media users. Complete parts a through c below.   a. Construct a 99​% confidence interval to estimate the actual proportion of social media users. A 99​% confidence interval to estimate the actual proportion has a lower limit of------ and an upper limit of------- ​(Round to three decimal places as​ needed.) b. What is the margin of error for this​ sample? c. Is there evidence that this proportion matches that of the overall population based on the​ sample?

A certain statistics instructor participates in triathlons. The accompanying table lists times​ (in minutes and​ seconds) he recorded while riding a bicycle for five laps through each mile of a​ 3-mile loop. Use a 0.05 significance level to test the claim that it takes the same time to ride each of the miles. Does one of the miles appear to have a​ hill?   LOADING...

You are a researcher studying the antler size of male Alaskan Moose in a certain Alaska location.  You gather a random sample of 18 male moose and record the width (in feet) of the antlers. The data is displayed in the table below.  Estimate the mean antler width of all Alaskan male moose in this area.  Use a 90% confidence level.   3.6 5.6 3.4 3.4 4 5.2 4.6 4.3 4.6 4.6 2.2 6.4 3.6 3.1 5.4 4.4 3.3 4.3       a)  Find the confidence interval:   < μμ <   b) What is the margin of error of your interval?  c) Interpret your 90% confidence interval in context.
