Okay, so for this problem, what it wanted you to do was it wanted to, and i'm just going to make this a little bit bigger so that you could see, it wanted to take the spreadsheet and answer some questions.
00:17
So the first thing it wanted you to do was construct a scatter diagram to represent the data graphically.
00:22
Focus on the temperature and the number of ice cream cones sold.
00:27
So i want to take this data here and i want to insert a scatter plot.
00:36
That's not the right one.
00:38
So if i click on scatterplot and then here we go.
00:43
And so it also wanted me to, and i'm just going to make this part a little bit smaller so i can fit in for the chart.
00:55
I can put in a title and this is about convenience store ice cream ice convenience ice creams sold per temperature and i'm just gonna abbreviate it there and so i can add an axes title so for the x -axis we are going to call it mean temperature in degrees celsius and then for the vertical axes i'm going to call it the number of ice cream sold and then it says comment on any apparent relation between the variables so for my relation with the variables, i'll do that one second, but it says develop an estimated regression equation for this data set.
02:26
So first of all, i want to draw a line.
02:31
So if i click on this and i click on trend line, we're going to do a linear trend line, and then there's the linear trend line.
02:39
And if i click on the line, it will give me a line.
02:53
It should give me a line of best fit.
02:58
Oh, here we go.
03:01
So display, so we can set an intercept.
03:05
We can display the equation.
03:09
But that's, see how if i click on this and it will change it according to if i set an intercept or not and i'm just going to move these equations here and here is my line of best fit and then if i go to let me just go back to this and my here we go i'm just trying to go back to i'm going to just make it bold.
04:10
If i go back to home and i make it bold and i'm just trying to fix this...
