alonzo describes a histogram as having a cluster from 20 - 50, a frequency of 0 from 10 - 20, and a peak at 40 - 50. which histogram is he describing? reading logs reading logs reading logs students students students 20 20 15 15 15 10 10 10 5 5 5 0 - 10 10 - 20 20 - 30 30 - 40 40 - 50 0 - 10 10 - 20 20 - 30 30 - 40 40 - 50 0 - 10 10 - 20 20 - 30 30 - 40 40 - 50 number of pages number of pages number of pages

Explanation:

Step1: Check cluster from 20 - 50

We need to find a histogram with a non - zero frequency in the 20 - 50 range.

Step2: Check frequency from 10 - 20

The frequency in the 10 - 20 range should be 0.

Step3: Check peak at 40 - 50

Look for a histogram with the highest bar in the 40 - 50 interval.

In the first histogram:

• There is a cluster from 20 - 50 (bars in 20 - 30, 30 - 40 and 40 - 50).
• The frequency from 10 - 20 is 0.
• The peak is at 40 - 50.

In the second histogram, the peak is not at 40 - 50. In the third histogram, there is a non - zero value in the 10 - 20 range.

Answer:

The first histogram.
