Question

what is the range?
stem
leaf 30|31|32|34|42|45|45|54|62|65

Explanation:

Step1: Find the maximum value

In a stem - and - leaf plot, the maximum value is formed by the largest stem and the largest leaf. The largest stem is \(6\) and the largest leaf is \(5\), so the maximum value \(M = 65\).

Step2: Find the minimum value

The smallest stem is \(3\) and the smallest leaf is \(0\), so the minimum value \(m=30\).

Step3: Calculate the range

The formula for the range \(R\) is \(R = M - m\). Substitute \(M = 65\) and \(m = 30\) into the formula: \(R=65 - 30\).

Answer:

\(35\)
