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.
I would say C, but it also might be d
Answer:
A
Step-by-step explanation:
The bars are of equal width and correspond to the equal class intervals, while the height of each bar corresponds to the frequency of the class it represents. The histogram is used for variables whose values are numerical and measured on an interval scale.
