Explanation / Answer

1.B 2.B 3.B 4.C 5.D 6.C 9.Referring to Table 13-3, theleast squares estimate of the slope is 2.5 10.Referring to Table 13-3, theleast squares estimate of the Y-intercept is 1 11.Referring to Table 13-3, theprediction for the number of job offers for a person with 2 co-opjobs is 6 12.Referring to Table 13-3, thetotal sum of squares (SST) is 13 13.Referring to Table 13-3, theregression sum of squares (SSR) is 12.5 14.Referring to Table 13-3, theerror or residual sum of squares (SSE) is 0.5 15.Referring to Table 13-3, thecoefficient of determination is 0.96 16.Referring to Table 13-3, thecoefficient of correlation is 0.98 Post the remaining seperatelythen we can answer.
