Question

does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria?
temperature (°f) frequency
40 - 44 1
45 - 49 0
50 - 54 6
55 - 59 14
60 - 64 7
65 - 69 6
70 - 74 1
does the frequency distribution appear to have a normal distribution?
a. no, the frequencies do not decrease from the maximum frequency to a low frequency.
b. no, the distribution does not appear to be normal.
c. yes, all the requirements are met.

Explanation:

In a normal distribution, frequencies should increase to a maximum and then decrease symmetrically. Here, the frequencies increase from 1 to 14 and then decrease, but the decrease is not symmetric. Also, the frequencies do not decrease smoothly from the maximum frequency to a low frequency in a symmetric - bell - shaped way as required by a normal distribution.

Answer:

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