Question

the prices of the 19 top-rated all-season tires for a specific tire size, are as follows. answer parts (a) - (c).

$88 $117 $98 $78 $82 $90 $91 $89 $91 $81
$109 $112 $101 $96 $85 $90 $75 $99 $90

a) determine \\(q_2\\).

\\(q_2 = \\)

Explanation:

Sort the data set

Using the Median Calculation knowledge point

$$ \text{Raw data: } 88, 117, 98, 78, 82, 90, 91, 89, 91, 81, 109, 112, 101, 96, 85, 90, 75, 99, 90 $$

$$ \text{Sorted data (19 values): } 75, 78, 81, 82, 85, 88, 89, 90, 90, 90, 91, 91, 96, 98, 99, 101, 109, 112, 117 $$
