Alright, here we have another great problem for a graphing calculator.
00:04
We have a table of data, and we're going to start by making a scatter plot.
00:08
So we go into the stat menu, and then we go into edit, and we type our data into list 1 and list 2.
00:16
Once we have that done, to turn on a scatter plot, we can go into the stat plot menu, which is 2nd .y equals, go into the menu for plot number 1, and turn it on, and make sure that it is a scatter plot using list 1 and list 2.
00:30
Once we have those settings, we can go into the zoom.
00:32
Menu and choose zoom stat which is zoom number nine and here's our scatter plot.
00:38
It does look like those points are falling along a line so i would say a linear model is appropriate.
00:45
For part b we want to find and graph the regression line so we go back to the stat menu over to calculate down to linear regression number four press enter.
00:55
Yes we want list one in list two we don't need to worry about frequency list and because we want to draw the graph we should store the regression equation in the y equals menu...
