Question

the stem - and - leaf plots compare the ages of 30 actors and actresses at the time they won an award.
complete parts a through d below.
a. what is the age of the youngest actor to win the award?
31 years old
b. what is the age difference between the oldest and the youngest actress to win an award?

Explanation:

Step1: Identify the youngest actor's age

From the stem - and - leaf plot for actors, the youngest age is \(21\) (since the stem is \(2\) and the leaf is \(1\)).

Step2: Calculate the age difference for part b

The oldest actress's age: from the stem - and - leaf plot for actresses, the stem is \(8\) and the leaf is \(0\), so the age is \(80\). The youngest actress's age: stem is \(1\) and leaf is \(4\), so the age is \(14\). The age difference \(d=80 - 14\).

Answer:

a. \(21\) years old
b. \(66\)
