Question

create a histogram with five intervals from this data set:
21, 37, 56, 87, 32, 45, 77, 71, 65, 67, 21, 34
step 1: find the minimum and maximum values.
minimum: 21 maximum: 87
step 2: round the minimum down to the nearest 10.
range minimum:

Explanation:

Step1: Identify the minimum value

The data set is \(21, 37, 56, 87, 32, 45, 77, 71, 65, 67, 21, 34\). The smallest value (minimum) is \(21\).

Step2: Round down to nearest 10

To round \(21\) down to the nearest 10, we look at the tens place. The number \(21\) is between \(20\) and \(30\), and rounding down gives \(20\). So the range minimum is \(20\).

Answer:

20
