The mean call length is a - 90 seconds, and the standard deviation is 6 - 120 seconds. 1. Let x be the sample mean from 10 randomly selected calls. What is the mean and standard deviation of the sampling distribution of x's, the means of all samples of size n - 10. 2. What can you say about the shape of the distribution of x? Explain. 3. Let x be the sample mean from 100 randomly selected calls. What is the mean and standard deviation of the sampling distribution of x's, the means of all samples of size n - 100. 4.
