Constructing a frequency distribution and a frequency histogram
In exercise 32 construct a frequency distribution and a frequency histogram for the data set using the indicated number of class.

(3) Determine the class interval (Cl), the width of classes of it may be the difference two succeeding class midpoints (CM). The CM is the average between the limits of a class. For each computation, CI must be a whole number. It can be obtained by the equation CI-R/K-101.5/10-10.15 (4) Take the frequency distribution for each set of data On the basis of this method, the frequency distribution is as follows: Table 8.1.

1. Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value tα/2, (b) find the critical value zα/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 95%, σ=3999 thousand dollars, and the histogram of 66 player salaries (in thousands of dollars) of football players on a team is as shown. 0 4000 8000 12000 16000 20000 0 10 20 30...
