Answer d

For the data set shown below, complete parts (a) through (d) below. 20 30 40 50 60 98 93 89 83 68 . . . (a) Use technology to find the estimates of Bo and By. Bo ~ bo = 114.2 (Round to two decimal places as needed.) By~ by = -.7 (Round to two decimal places as needed.) (b) Use technology to compute the standard error, the point estimate for o. Se = 3.8644 (Round to four decimal places as needed.) (c) Assuming the residuals are normally distributed, use technology to determine spy . Sb. = 0.1221 (Round to four decimal places as needed.) (d) Assuming the residuals are normally distributed, test Ho: B, = 0 versus H, : B, #0 at the a = 0.05 level of significance. Use the P-value approach. Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.)
