the table below shows the frequency distribution of the rainfall on 52 consecutive sundays in a certain city. use the frequency distribution to construct a histogram. do the data appear to have a distribution that is approximately normal?\nclass frequency\n0 - 0.19 20\n0.20 - 0.39 13\n0.40 - 0.59 4\n0.60 - 0.79 2\n0.80 - 0.99 5\n1.00 - 1.19 3\n1.20 - 1.39 5
Answer
Explanation:
Step1: Recall normal - distribution shape
A normal - distribution histogram has a bell - shaped curve, symmetric about the mean, with most of the data in the middle and tapering off at the ends.
Step2: Analyze the given frequency distribution
The frequencies start high for the lower rainfall classes (0 - 0.19 with frequency 20), then decrease, and then have some non - zero frequencies for the higher classes.
Step3: Match with histogram options
The histogram should have a peak for the lower classes and then decrease gradually. Option A shows a histogram that starts high for the lower values of rainfall (0 - 0.19) and then decreases as the rainfall values increase, which is consistent with the given frequency distribution.

A.
