Question

does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria? temperature (°f) 50 - 54 55 - 59 60 - 64 65 - 69 70 - 74 75 - 79 80 - 84 frequency 3 0 6 13 7 5 1 a. no, the frequencies do not decrease from the maximum frequency to a low frequency b. yes, all the requirements are met c. no, the distribution does not appear to be normal

Explanation:

Step1: Recall normal - distribution criteria

For a frequency distribution to be approximately normal, the frequencies should first increase to a maximum and then decrease symmetrically. Looking at the given frequencies 3, 0, 6, 13, 7, 5, 1, the frequencies do not follow the pattern of increasing to a maximum and then decreasing in a symmetric fashion.

Answer:

A. No, the frequencies do not decrease from the maximum frequency to a low frequency
