The following table contains a set of randomly generated values for X and Y, using Excel functions

Y = 5*rand() and X = 2*rand().

(a) Show a scatter plot of these data and discuss whether there is a linear equation that might describe the relationship between X and Y.

(b) Use Excel to develop a regression model and show the results.

(c) Use the above functions (i.e., Y = 5*rand() and X = 2*rand()) to generate 10 more data points and run a regression again. Show your results.
