1 60 points Part 1 of 6 O Points: 0 of 1 Save The mean annual salary of classroom teachers is approximately normal with a mean of $45,556. Assume a standard deviation of $8400. Do the following for the variable "annual salary" of K classroom teachers. a. Determine the sampling distribution of the sample mean for samples of size 64. The sample mean is kx =| VI V I.

The study revealed that the overall physical activity of obese young adults has a mean of u = 325 com and a standard deviation of = 90 cpm. In a random sample of n = 100 obese young adults, consider the sample mean counts per minute, x. Click the icon to view the table of normal curve areas. a. Describe the sampling distribution of x.
