Question

the table below shows the frequency distribution of the rainfall on 52 consecutive fridays 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\tfrequency
0 - 0.19\t25
0.20 - 0.39\t12
0.40 - 0.59\t3
0.60 - 0.79\t2
0.80 - 0.99\t4
1.00 - 1.19\t5
1.20 - 1.39\t1

choose the correct histogram below.

Explanation:

Step1: Analyze class - frequency pairs

We have class intervals and their corresponding frequencies. For example, for the class $0 - 0.19$, the frequency is 25.

Step2: Match with histograms

In histogram A, the bar for the class $0 - 0.19$ has a height corresponding to a frequency of around 25, the bar for $0.20 - 0.39$ has a height corresponding to a frequency of around 12, and so on which matches the given frequency - distribution table. In histogram B and C, the frequencies for the different classes do not match the values in the table.

Answer:

A
