Referring to the above outcome answer the following questions:


a)    Write the estimated model in equation form, stating the appropriate coefficients


b)    Interpret the slope coefficient


c)    Is the number of downloads for the trial version of his new shareware a significant independent variable in this model? Explain why or why not.


d)    What is the value of the coefficient of determination here? What does it mean for this problem?


e)    What is the value of the standard error of the estimate? What does it indicate?


f)    What are the lower and upper limits of the 95% confidence interval estimate for the mean change in revenue as a result of one thousand increase in the number of downloads?


g)    State the null and alternative hypothesis for testing whether there is a linear relationship between variables


h)    What is the critical value for testing whether there is a linear relationship between variables at a 5% significance level?


Your presentation should outline:


-    how this problem was tackled,


-    the methodology used,


-    the justification for the solution reached and


-    an interpretation of your results.
