Question
Suppose a variable X has sample
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 200.76
