Galaxy velocity study. Refer to the Astronomical Journal (July 1995) study of galaxy velocities, presented in Exercise 2.100 (p. 74). A histogram of the velocities of 103 galaxies located in a particular cluster named A2142 is reproduced below. Comment on whether or not the galaxy velocities are approximately normally distributed.

Exercise 2.100
Examine the sample data in the following table:
We need at least 10 more requests to produce the solution.
0 / 10 have requested this problem solution
The more requests, the faster the answer.
