Suppose a variable X has sample mean 200 and standard deviation 10 and the variable Y has sample mean 4000 with standard deviation 100 and when you plot the variables X and Y the points form a perfect positive line so you can predict the future value of Y given a future value of x using the formula Future value of Y = mean of Y + standard deviation of Y* (zscore of X) predict the future value of Y if x is 200.35 Note that you will also have to plot points in the week 6 test and final exam, refer to the week 6 test and the sample final exam click here if you need a guide Answer:
