The following data are observations y on a dependent random variable Y taken at various levels of
Question:
(a) Estimate the linear relationship by the method of least squares, and forecast the value of Y when x = 10.
(b) Find a 95 percent confidence interval for the expected value of Y at x* = 10.
(c) Find a 95 percent prediction interval for a future observation to be taken at x+ = 10.
(d) For x+ = 10, P+ = 0.90, and 1 α = 0.95, find a simultaneous Tolerance interval for the future value of Y+. Interpolate if necessary.
Future value (FV) is the value of a current asset at a future date based on an assumed rate of growth. The future value (FV) is important to investors and financial planners as they use it to estimate how much an investment made today will be worth...
