Question

Does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant​ criteria? Temperature ​(°​F) Frequency 40-44 2 45-49 0 50-54 5 55-59 14 60-64 7 65-69 6 70-74 1 Does the frequency distribution appear to have a normal​ distribution?

Answer 1

Answer:

The frequency distribution does NOT appear to have a normal distribution using a strict interpretation of the relevant criteria.

Step-by-step explanation:

Note: See the attached excel file for the Graph of Temperature ​(°​F) vs. Frequency.

A normal distribution refers to a bell-shaped distribution that begins at a low value, grows to a maximum value, and then declines to a low value again. It is a symmetric and a single-peaked distribution.

The fact that the frequency in the data in this question first fell from 2 to 0 before rising again to 5 indicates that it is neither a bell-shaped distribution nor a single-peaked distribution. This is also corroborated by the Graph of Temperature ​(°​F) vs. Frequency in the attached excel file which shows that there are two peaks which are 2 and 14.

Therefore, the frequency distribution does NOT appear to have a normal distribution using a strict interpretation of the relevant criteria.
