Data on salaries in the public school system are published annually by a teachers' association. The mean annual salary of (public) classroom teachers is $53.6 thousand. Assume a standard deviation of $7.2 thousand. Complete parts (a) through (e) below. a. Determine the sampling distribution of the sample mean for samples of size 64. The mean of the sample mean is μ = $. (Type an integer or a decimal. Do not round.) The standard deviation of the sample mean is o=$. (Type an integer or a decimal. Do not round.) b. Determine the sampling distribution of the sample mean for samples of size 256.
