1. Suppose an x distribution has mean LaTeX: \muμ= 10 and a standard deviation of 2. Random sample sizes of 25 are drawn.

Describe the x-bar (mean of the sample) distribution and mean and standard deviation of the distribution.

Find the z-values and the probability that x-bar will be between 9.8 and 10.6.
