# Question

For the following population of N = 6 scores: 3 1 4 3 3 4

a. Sketch a histogram showing the population distribution.

b. Locate the value of the population mean in your sketch, and make an estimate of the standard deviation (as done in Example 4.2).

c. Compute SS, variance, and standard deviation for the population. (How well does your estimate compare with the actual value of s?)
