And here's another shmoopy question for ya.

00:06

The following graph shows points representing the relationship between the amount of time

00:09

spent walking per week and cholesterol levels of various people. 

00:12

The people who don’t walk at all… are on an entirely different, much more depressing graph.

00:17

Based on this graph, a person who walks about 2.5 hours per week can expect

00:21

to have a cholesterol level of… what?

00:25

And here are the potential answers...

00:33

Scatter plot question. These are all about just making educated guesses.

00:37

Emphasis on… educated.

00:40

First let’s find the key points – the question asks about what happens after 2 and

00:44

a half hours or 150 minutes of walking…

00:47

…so we get a line starting here… as each block is 15 minutes.

00:52

If we draw the line upwards, we cross dots around here…

00:55

…so if we draw a horizontal line back to the y-axis…

00:58

…we get to a spot about half way between 120 and 240

01:02

or at about the 180 milligrams per deciliter line.

01:05

So the answer is B.

01:07

As in… “Butter pecan.”
