For the data set shown below, complete parts (a) through (d) below. x y 20 102 30 95 40 91 50 81 60 68 (a) Use technology to find the estimates of beta 0 and beta 1. beta 0 ~ b 0=_____(Round to two decimal places as needed.) beta 1 ~ b 1=_____(Round to two decimal places as needed.) (b) Use technology to compute the standard error, the point estimate for o' (o with a little tag on the top) S e =_____(Round to four decimal places as needed.) (c) Assuming the residuals are normally distributed, use technology to determine Sb1 Sb1 =_____ (Round to four decimal places as required) (d) Assuming the residuals are normally distributed, test H0: B1 =0 versus H1:B1 =/ at the a = 0.005 level of significance. Use the P - value approach. The P - value for this test is _____ (Round to three decimal places as needed.
