Question

the table below shows the frequency - distribution of the rainfall on 52 consecutive mondays in a certain city. use the frequency distribution to construct a histogram. do the data appear to have a distribution that is approximately normal?

class	frequency
0.20 - 0.39	11
0.40 - 0.59	6
0.60 - 0.79	3
0.80 - 0.99	8
1.00 - 1.19	1
1.20 - 1.39	1

Explanation:

Step1: Recall histogram - construction rules

The x - axis represents the class intervals and the y - axis represents the frequency. For the class interval \(0 - 0.19\), the frequency is 22, for \(0.20 - 0.39\) it is 11, for \(0.40 - 0.59\) it is 6, for \(0.60 - 0.79\) it is 3, for \(0.80 - 0.99\) it is 8, for \(1.00 - 1.19\) it is 1 and for \(1.20 - 1.39\) it is 1.

Step2: Analyze each option

In option A, the frequencies for the class intervals do not match the given data. In option B, the frequencies for the class intervals also do not match. In option C, the bar - heights (frequencies) for each class interval match the given frequency distribution.

Answer:

C
