- The t distribution is appropriate to use when?In the world populations, normal body temperature follows a normal distribution with mean = 98.6 degrees F and a standard deviation of 0.6. The mean body temperature will be determined for a randomly selected group of 14 individuals. Is Central Limit Theorem can be applied here, Blank 1Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 100 pounds and a standard deviation of 38.5 pounds. Random samples of size 18 are drawn from this population and the mean of each sample is determined. μx=nothing
- (d) Calculate the semi-interquartile range of the distribution.Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 109 pounds and a standard deviation of 38.3 pounds. Random samples of size 15 are drawn from this population and the mean of each sample is determined. μx=nothing σx=nothing (Round to three decimal places as needed.) Sketch a graph of the sampling distribution. Choose the correct graph below. A. 109 89.2128.8 x A normal curve is over a horizontal x overbar axis labeled from 89.2 to 128.8 and is centered on 109.

Unknown to the man, three of these can contains an incorrect mix of paint. For this weekend’s big project, the man randomly selects four of these 1-gallon cans to paint his mother’s living room. Let x = the number of the paint cans selected that are defective. Unknown to the man, x follows a hypergeometric distribution. Find the mean of this distribution. A) 12 B) 3 C) 1 D) 4
