Consider the paired sample {(3, 1),(3, 5),(6, 6),(6, 8),(7, 10)}. Do the following by hand (you may use a basic calculator, but not a statistical program). (a) Find estimates βˆ 0 and βˆ 1 of the regression parameters β0 and β1. (b) Make a rough sketch of the data and regression line. (c) Predict the value of y when x = 5. (d) Predict the value of y when x = 15. (e) Which prediction (part c or d) do...

3, 7, 8, 5, 6, 4, 9, 10, 7, 8, 6, 5 Using the previous question 's scores, If three points were added to every score in this distribution, what would be the new mean? If three points were added to every score in this distribution, what would be the new standard deviation. Remember, you have already calculated population standard deviation in a previous problem. This problem requires two answers.
