ANSWER BOTH PARTS I & II.

Part I: Computing z - scores

Compute the z - scores for every X in the two distributions you see below (SHOW AS MUCH WORK AS POSSIBLE)

• Assume these two distributions are populations
• Remember that you'll need the mean and standard deviation ( and ) for the populations.
• For each distribution do the following three steps
  1. First calculate the mean of each distribution
  2. Then calculate the standard deviation () using the population formula given below.
