The heights offullgir grown trees of a specic species are normally distributed, with a mean of 53.0 feet and a standard deviation of?.l]l] feet. Random samples of size 20 are drawn from the population. Use the central limit theorem to nd the mean and standard error of the sampling distribution. Then sketch a graph of the sampling distribution. T' The mean ofthe sampling distribution is p; = D. The standard error of the sampling distribution is 5i = D. (Round to two decimal places as needed.) Choose the correct graph of the sampling distribution below. Oh 0e on s ' a Q Q s. a - a: - a - :3: X ' X ' X ' 49.9 53.0 56.1 2 l] 2 39.0 53.0 67.0 rn
