If the coefficient p, has a nonzero value, then it is helpful in predicting the value of the response variable. If B, = 0, it is not helpful in predicting the value of theresponse variable and can be eliminated from the regression equation. To test the claim that B, = 0 use the test statistic t= (b1 - 0) /Sp. Critical values or P-valuescan be found using the t distribution with n - (k 1) degrees of freedom, where k is the number of predictor (x) variables and n is the number of observations in the sample. The standard error so,is often provided by software. For example, see the accompanying technology display, which shows that sp, = 0.072654994 (foundin the column with the heading of "Std. Err." and the row corresponding to the first predictor variable of height). Use the technology display to test the claim that B, = 0. Also test the claim that ß2 = 0. What do the results imply about the regression equation?
