Solution
Solution Steps
Step 1: Identify the Frequency Distribution
The table provides the frequency distribution of rainfall on 52 consecutive Mondays in a certain city. The classes and their corresponding frequencies are:
0.00 - 0.19: 23
0.20 - 0.39: 13
0.40 - 0.59: 6
0.60 - 0.79: 2
0.80 - 0.99: 4
1.00 - 1.19: 1
1.20 - 1.39: 3
Step 2: Construct the Histogram
To construct the histogram, plot the frequency of each class interval on the y-axis against the class intervals on the x-axis.
Step 3: Choose the Correct Histogram
Compare the given histograms (A, B, and C) with the frequency distribution:
Histogram A: Shows a high frequency for the last class interval, which does not match the given data.
Histogram B: Shows a decreasing trend from the first class interval to the last, which matches the given data.
Histogram C: Shows a high frequency for the first class interval and a low frequency for the rest, which does not match the given data.
