Problem 13BSC

Earthquake Magnitudes Use the frequency distribution from Exercise 23 in Section 2-2 to construct a histogram. Using a loose interpretation of the requirements for a normal distribution, do the magnitudes appear to be normally distributed? Why or why not?

Step-by-Step Solution:

Step 1 of 1

 Mag(x) 0.7 0.74 0.64 0.39 0.7 2.2 1.98 0.64 1.22 0.2 1.64 1.32 2.95 0.9 1.76 1.01 1.26 0 0.65 1.46 1.62 1.83 0.99 1.56 0.4 1.28 0.83 1.34 0.54 1.25 0.92 1 0.79 0.79 1.44 1 2.24 2.5 1.79 1.25 1.49 0.84 1.42 1 1.25 1.42 1.35 0.93 0.4 1.39

The width of each bar has to be equal and the height has to equal the frequency:

This is in the form,

 C - I Frequency 0 - 0.5 5 0.5 - 1 18 1 - 1.5 19 1.5 - 2 7 2 - 2.5 3 2.5 - 3 2

Yes, because the histogram is roughly bell shaped.
