The total frequency of the data whose histogram is shown below is approximately

A)11 
B)22

Quizplus · Accepted Answer

The total frequency of a histogram is equal to the sum of the frequencies of all the bars. In this case, we can count the frequency of each bar by counting the number of data points that fall within each interval. Doing so, we have:

Bar 1: 2 data points 
Bar 2: 6 data points 
Bar 3: 7 data points 
Bar 4: 7 data points

Adding up these frequencies, we get:

2 + 6 + 7 + 7 = 22

Therefore, the total frequency of the data is approximately 22, which means the correct answer is B.
