Question

the data represents the number of minutes people spent driving one week. is this distribution symmetrical?

Explanation:

Step1: Analyze the histogram's shape

A symmetrical distribution has data evenly distributed around a central point, with the left and right sides mirroring each other. Here, the left bar (40 - 90 minutes) is very tall (height 8), while the middle (140 - 190) and right (240 - 290) bars are short (height 2 each), and there's a gap between 90 - 140 and 190 - 240. The left side is much more populated, and the right side doesn't mirror the left in height or position.

Step2: Conclude symmetry

Since the left and right sides of the distribution (around a potential center) do not have similar shapes or frequencies, the distribution is not symmetrical.

Answer:

No, the distribution is not symmetrical.
