Question

A researcher surveyed 146 adults and recorded the number of miles they drove their car in one year. The results are in the boxplot above and the annual number of miles is measured in 1000's.

Answer 1

Explanation:

range : 6.5 to 23.5 thousand miles.

= 23.5 - 6.5 = 17 thousand miles.

maximum : 23.5 thousand miles

25% of the data is above 16.4 thousand miles.

75% of the data is above 8.6 thousand miles.

and therefore, 75% of the data is between 8.6 and 23.5 thousand miles.
