Part 2
Using the fundamental equations for the slope and mtcrcept found in your book (and in many other places as well) re-compute the slope and intercept for the data from Part I.
Part 3
Using the same data provided in Pan I complete a simple linear regression in your calculator and report and define the critical values that your calculator provides when it completes a linear regression.
Part 4
Visit one or both of the following web sites. Enter the Pan I data, get the regression parameters and play a little to see how additional data points change the equation and critical parameters. Print a screen shot to show your efforts.
Bonus 2
Find another online application (or one for a smartphone) that can perform simple linear regression. List the source (website. name. version. etc.). Enter the part I data, get the regression parameters and play a little to see how additional data points change the equation and critical parameters. Print a screen shot (or photo) to show your efforts.
Of course you should get the same answers each way you do the regression.
