Chapter 1: Q 56. (page 46)

Drive time Professor Moore, who lives a few miles outside a college town, records the time he takes to drive to the college each morning. Here are the times (in minutes) for 42 consecutive weekdays:

Make a histogram of these drive times. Is the distribution roughly symmetric, clearly skewed, or neither? Are there any clear outliers?

Short Answer

Expert verified

There are no outliers or extreme values.

Step by step solution

01

Given information

8.257.838.308.428.508.678.179.009.008.177.92
9.008.509.007.757.928.008.088.428.758.089.75
8.337.837.928.587.838.427.757.426.757.428.50
8.6710.178.758.588.679.179.088.838.67

02

Concept

The formula used: Range=Minimum value-Maximum value

03

Explanation

The Histogram of the drive time is

The distribution's form appears to be closer to symmetric. It is a left-skewed distribution in particular, with the data centering at 8.4 minutes.

Therefore,

Maximum value = 10.17

Minimum value=6.75

Range=Minimum value-Maximum value

Range=10.17-6.75=3.42

Therefore, there are no outliers or extreme values.
