Find the mean and standard deviation of a sampling distribution of sample means with sample size n = 36. %3D H=(Simplify your answer.) %3D (Simplify your answer)The standard deviation of the given the data (14, 13, 16, 9, 3} is ♦ If the average American male is 5'10" and the standard deviation is 3", then Yao Ming who is 7'6" is within ◆ standard deviations of the mean? An outlier is an extreme value that is significantly less or more than the rest of the data. In the data below take out the outlier, then calculate using a statistics calculator or spreadsheet, the standard deviation of the heights of 15 soda cans. {92.8, 92.8, 92.9, 92.9, 92.9, 92.8, 92.7, 92.9, 92.1, 92.7, 92.8, 92.9, 92.9, 92.7, 92.8} Round to the nearest 100th.

(Round your answer to two decimal places.) 3.answer only c-e In the 1992 presidential election, Alaska's 40 election districts averaged 1939 votes per district for President Clinton. The standard deviation was 550. (There are only 40 election districts in Alaska.) The distribution of the votes per district for President Clinton was bell-shaped. Let X = number of votes for President Clinton for an election district. (Source: The World Almanac and Book of Facts) Round all answers except part e. to 4 decimal places.a. What is the distribution of X? X ~ N(40, 550)c. Find the probability that a randomly selected district had fewer than 1961 votes for President Clinton. ___________d.
