Temperature X = -8 -4 0 4 8
Flavor Y = 11.7 11 10.2 9 7.8
Using matrix notation for the regression model Y=XBeta+ Epsilon
Obtain the following:
a. Vector of estimated regression coefficients
b. estimated variance-covariance matrix of b
c. Point estimate of E(Yh), when Xh=-6
d. Estimated variance of Yh, when Xh = -6
e. Interval estimate of E(Yh) when Xh = -6. Should we call it a confidence or prediction interval? Use Alpha = 0.05.
