A recent study involving a sample of 3,000 vehicles in California showed the following statistics related to the number of miles driven per day: Q1 = 12, Q2 = 45, and Q3 = 56. Based on these data, if a box and whisker plot is developed, the upper limit value is 122 miles.

Question

Quizplus · Accepted Answer

The upper limit value in a box and whisker plot is typically 1.5 times the interquartile range (IQR) above the third quartile (Q3). In this case, the IQR is Q3 - Q1 = 56 - 12 = 44. Therefore, the upper limit value would be 1.5 * 44 + 56 = 122 miles.
