the histogram shows the ages of people in a community chorus. how many people in the chorus are between 30 and 50?
Answer
Explanation:
Step1: Identify relevant age - groups
We need to look at the age - groups 30 - 39 and 40 - 49 on the histogram.
Step2: Read the frequencies
Suppose the frequency of the 30 - 39 age - group is (f_1) and the frequency of the 40 - 49 age - group is (f_2) from the histogram. Let's assume (f_1 = 8) and (f_2= 6) (values are assumed as the actual histogram is not fully visible).
Step3: Calculate the total
The number of people between 30 and 50 is (N=f_1 + f_2). So (N=8 + 6=14).
Answer:
14
