Find the mean, variance and standard deviation of X. Find the mean, variance and standard deviation of Y. Let Z be a new RV which is simply 5 added to each score from which X was originally chosen. Find the mean, variance, and standard deviation of Z. Check that the following rules agree with your calculations. Note that c=5, X+c is the Z.

(60pts) Suppose X is a random variable that has normal distribution with mean = 4 and standard deviation (SD) = 2. Do the following: Find = Find = Find = Find constant c such that X will be in the interval [4 - c, 4 + c] with probability 90%. So . Find x* such that . Since But . So (x*-4)/2=1.645 and x* = 7.29. Suppose a constant c makes . What ...

When the standard deviation is large, the scores are more widely spread out on average from the mean. The standard deviation is calculated to find the average distance from the mean. Practice Problem #1: Calculate the standard deviation of the following test data by hand. Use the chart below to record the steps.
