Normal Distribution Instead of using the hand lengths in Exercise 1, a much larger sample of hand lengths is used and a frequency distribution is created. The frequencies listed in order are 1, 8, 56, 237, 382, 228, 48, 4, 1. Does it appear that the sample is from a population having a normal distribution? Explain.

Answer :

Step 1 of 1 :

From the given information the listed frequency are

1, 8, 56, 237, 382, 228, 48, 4, 1.

Yes.It appear that the sample is from a population having a normal distribution.

The frequencies increase to a maximum, and then they decrease.

Also, the frequencies preceding the maximum are roughly a mirror image of those that follow the maximum.
