Question

does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria?
temperature (°f) frequency
50 - 54 2
55 - 59 0
60 - 64 5
65 - 69 14
70 - 74 9
75 - 79 6
80 - 84 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:

For a normal distribution, frequencies should increase to a maximum and then decrease symmetrically. Here, the frequencies increase from 2 to 14 and then decrease, but the distribution is not symmetric. For example, the frequency for 50 - 54 is 2 and for 80 - 84 is 1, and the shape is not bell - shaped as required for a normal distribution.

Answer:

B. No, the distribution does not appear to be normal.
