The Minnesota State Fishing Bureau has contracted with a university biologist to study the length of walleyes

Question:

The Minnesota State Fishing Bureau has contracted with a university biologist to study the length of walleyes (fish) caught in Minnesota lakes. The biologist collected data on a sample of 1,000 fish caught and developed the following relative frequency distribution:
Class Length (inches) Relative Frequency fi
8 to less than 10……………………………0.22
10 to less than 12…………………………..0.15
12 to less than 14…………………………..0.25
14 to less than 16…………………………..0.24
16 to less than 18…………………………..0.06
18 to less than 20…………………………..0.05
20 to less than 22…………………………..0.03
a. Construct a frequency distribution from this relative frequency distribution and then produce a histogram based on the frequency distribution.
b. Construct a pie chart from the relative frequency distribution. Discuss which of the two graphs, the pie chart or the histogram, you think is more effective in presenting the fish length data.
