1) Do the parameters of the sampling distribution of the sample mean change for different types of population (e.g., skewed vs. symmetric) and different sample sizes? Explain.

2)Let

\fPopulation Distribution for Time spent on hold 0.10 0.08 0.08 Value of density curve 0.04 0.02 0. 00 10 15 20 25 30 Time Spent on hold (hours)
