Question

For a sample of similar sized all-electric homes, the march electric bills were (to the nearest dollar): $212, $191, $176, $129, $106, $92, $108, $109, $103, $121, $175, and $194. what is the range? $112 $100 $130 $120

Answer 1

Answer: The range of the given data is $120.

Explanation:

For a set of observations, we know that the range of the set is given by:-

`\text{Range}=\text{Largest observation - Smallest observation}`

In the given data , the largest data value= $212

The smallest value= $92

Therefore, the range of the given observations is given by:-

`\text{Range}=\$212-\$92=\$120`

Hence, the range of the given data is $120.
