00:01 You're given a set of data and we want to put this data into list one and this into list two.
00:06 Assuming you have a ti -84, t -i -83, and we have 20 -20, we have 10 -20.
00:14 We have 30 -30, 40, 50, 60, 60, and 70 -80.
00:25 And it's always good to look at a graph of this once you put that data into list one and list two to look at a stat plot.
00:30 And your first question asked to find the correlation coefficient.
00:34 Well, i used my lin reg, and you will find that the a plus bx is the form that we want to use in statistics, although you have two different linear regs.
00:45 And that correlation coefficient comes out to be 0 .9743.
00:51 So it is quite close to one.
00:53 Part b, you want to find the regression equation, and your y hat will equal 4 .2...
