Question

the director of a community sports camp records the daily attendance. the histogram shows the data.

1. how many days have at least 70 campers?

a. 16 days

1. the camp can have at most 89 campers. how does that information help explain the shape of the histogram?

every camp size is equally common.
the most common camp size is when the camp is full.
the least common camp size is when the camp is full.

Explanation:

Step1: Identify relevant bars

Bars for 70 - 79 and 80 - 89 campers.

Step2: Sum frequencies

Frequency for 70 - 79 is 6, for 80 - 89 is 10. Sum: \(6 + 10=16\).

Since the camp can have at most 89 campers, the highest - attendance bar (80 - 89) represents full - capacity days. This makes the most common camp size when full, as the 80 - 89 bar has the highest frequency.

Answer:

16 days
