Table Step 1 of 5: Calculate the sum of squared errors (SSE). Use the values b0=4.7893 and b1=0.4164 for the calculations. Round your answer to three decimal places.

Step 2 of 5: Calculate the estimated variance of errors, s2e . Round your answer to three decimal places.

Step 3 of 5: Calculate the estimated variance of slope, s2b1 . Round your answer to three decimal places.

Step 4 of 5: Construct the 95% confidence interval for the slope. Round your answers to three decimal places. (Lower endpoint and upper endpoint)
