Expand Suppose that heights of male collegiate basketball players in a country are normally distributed with a mean of 75 in and a standard deviation of 3.6 in. A researcher wants to determine if the mean height of male collegiate basketball players in one particular conference is different from the national average. She obtains email addresses for all of the players in this conference and emails them asking for them to reply with their height Of the 573 emails she...
1/ The height of high school basketball players is known to be normally distributed with a standard deviation of 1.75 inches. In a random sample of eight high school basketball players, the heights (in inches) are recorded as 75, 82, 68, 74, 78, 70, 77, and 76. Construct a 95% confidence interval on the average height of all high school basketball players.

Find the mean height. Round your answer to one decimal place. Height (in.) Frequency 70 - 71 72-73 74 - 75 76 - 77 78 - 79 80 - 81 82-83 2 5 9 13 8 4 2
Listed below are the heights of candidates who won elections and the heights of the candidates with the next highest number of votes. The data are in chronological order, so the corresponding heights from the two lists are matched. Assume that the paired sample data are simple random samples and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval estimate of the mean of the population of all "winner/runner-up" differences. Does height appear to...
