Question

The price of 500 ml plastic containers from various stores is listed. Which of the following gives the range of the data, if each price is increased by 2 dollars?

• A. 4 dollars
• B. 6 dollars
• C. 7 dollars
• D. 9 dollars

Answer 1

The correct option is C 7 dollars

The given data set is

12, 15, 11, 13, 14, 8

It is given that each price is increased by 2 dollars.

Hence, the new data set is

14, 17, 13, 15, 16, 10

$\because$ Range = Maximum value - Minimum value

Here,
Maximum value = 17

Minimum value = 10

$\therefore$ Range = 17 - 10
= 7
