THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
The model y = β0 + β1X1 + β2X2 + ε was fitted to a sample of 25 families in order to explain household milk consumption: where y = Milk consumption,in quarts,per week,x1 = Weekly income,in hundreds of dollars,and x2 = Family size.The least squares estimates of the regression parameters were b0 = -0.03,b1 = 0.05,and b2 = 1.1,with coefficient standard errors
= 0.02;
= 0.38.The total sum of squares and the error sum of squares were found to be 165.8 and 66.32 respectively.
-Set up the analysis of variance table for testing H0 : β1 = β2 = 0 against H1 : At least one βj ≠ 0,(j = 1,2).
Football Players

Standard Deviation
A measure of the amount of variation or dispersion in a set of values, indicating how spread out the data points are from the mean.
Normally Distributed
A distribution where probabilities are mirrored on either side of the mean, illustrating higher frequency of events near the average.
