Question

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? three histograms labeled reading logs with x - axis number of pages (bins: 0 - 10, 10 - 20, 20 - 30, 30 - 40, 40 - 50) and y - axis students are shown, each with different bar heights for the bins.

Explanation:

Step1: Check frequency from 10 - 20

Alonzo says frequency from 10 - 20 is 0. In the second histogram, 10 - 20 has non - zero frequency. So, the second histogram is eliminated.

Step2: Check peak at 40 - 50

In the third histogram, the peak is at 30 - 40. But Alonzo says peak is at 40 - 50. So, the third histogram is eliminated.

Step3: Verify cluster from 20 - 50

The first histogram has non - zero frequencies from 20 - 50 (20 - 30, 30 - 40, 40 - 50), frequency 0 from 10 - 20 and peak at 40 - 50.

Answer:

The first histogram (the one on the left)
