Answer:

Step-by-step explanation:

Given are the top 40 stocks on the over-the-counter (OTC) market, ranked by percentage of outstanding shares traded on one day last year

We have to construct a relative frequency histogram.

Frequency Table

Class Count

2-3.69 19

3.7-5.39 12

5.4-7.09 5

7.1-8.79 3

8.8-10.49 0

10.5-12.19 1

Your Histogram

Mean 4.387

Standard Deviation (s) 1.87138

Skewness 1.95377

Kurtosis 5.43198

Lowest Score 2.61

Highest Score 11.88

Distribution Range 9.27

Total Number of Scores 40

Number of Distinct Scores 39

Lowest Class Value 2

Highest Class Value 12.19

Number of Classes 6

Class Range 1.7

Frequency histogram is attached

More than 40% is approximately 21

i.e. [tex]21/40 = 0.525[/tex]
