Answer:
a. $120
Explanation:
The range of a data set is the difference between the minimum value and maximum value of the data set.
The sample of sample of March electric bills amounts for all-electric homes of similar sizes (to the nearest dollar): $212,
$191,
$176,
$129,
$106,
$92,
$108,
$109,
$103,
$121,
$175 and
$194.
To find the range, we must first rearrange in order.
Let us arrange from least to highest.
92,103,106,108,109,121,129,175,176,191,194,212
The least bill is $92
The highest bill is $212
The range is 212-92=120
