Okay, so i see that you need help with this problem, and it says managing diabetes.
00:04
People with diabetes measure their fasting plasma glucose, the fpg, measured in units of milligrams per milliliter after fasting at least eight hours.
00:14
Another measurement made at regular medical checkups is called hba.
00:19
This is roughly the percent of red blood cells that have a glucose molecule attached.
00:27
It measures average exposure to glucose over.
00:30
A period of several months.
00:32
The table below gives the data on both hba and fpg for 18 diabetic five months after they have completed a diabetes education class.
00:45
So it says make a scatterplot with hba as the explanatory variable.
00:51
Describe what you see.
00:52
So explanatory variable, that is the independent variable.
00:56
So i'm going to insert here a scatter plot.
01:01
Based off of this data.
01:04
And so then it appears that there is a positive correlation, but it's very weak.
01:13
If i insert a trend line, this is what the trend line would look like.
01:23
And it is going in a positive direction, but again, it is very weak.
01:28
So it says subject 18 is an outlier in the x direction...
