The heights of 1000 students are approximately normally distributed with a mean of 174.5 centimeters and a standard deviation of 7.5 centimeters. Suppose 200 random samples of size 6 are drawn from this population and the means recorded to the nearest tenth of a centimeter. Determine (a) the mean and standard deviation of the sampling distribution of X¯; (b) the number of sample means that fall between 172.5 and 175.8 centimeters inclusive; (c) the number of sample means falling below...

The heights of fully grown trees of a specific species are normally distributed, with a mean of 61.0 feet and a standard deviation of 6.00 feet. Random samples of size 19 are drawn from the population. Use the central limit theorem to find the mean and standard error of the sampling distribution. Then sketch a graph of the sampling distribution. The mean of the sampling distribution is ?. The standard error of the sampling distribution is ?
