Answer 2

Given,

Ervin bowled 7 games last weekend. His scores are: 155, 165, 138, 172, 127, 193, 142.

To Find,

What is the range of Ervin's scores?

Solution,

We can solve the question as follows:

It is given that we have to find the range of Ervin's scores from his scores: 155, 165, 138, 172, 127, 193, 142.

$Ervin's\: scores = 155, 165, 138, 172, 127, 193, 142$

The range of a given set of observations is equal to the difference between the highest observation and the lowest observations.

$Range = Highest\: observation - Lowest\: observation$

In the given data,

$Highest\: observation = 193$

$Lowest\: observation = 127$

Therefore,

$Range = 193 - 127 = 66$

Hence, the range of Ervin's scores is 66.
