Step 1 of 5:

Calculate the sum of squared errors (SSE). Use the values b0=4.1353 and b1=−0.2442 for the calculations. Round your answer to three decimal places.

Step 2 of 5:

Calculate the estimated variance of errors, s^2e. Round your answer to three decimal places.

Step 3 of 5:

Calculate the estimated variance of slope, s^2b1. Round your answer to three decimal places

Step 4 of 5:

Construct the 98% confidence interval for the slope. Round your answers to three decimal places.

Step 5 of 5:

Construct the 80% confidence interval for the slope. Round your answers to three decimal places.

Step 1 of 5:

Calculate the sum of squared errors (SSE)

Step 1 of 5: Calculate the sum of squared errors (SSE) =0.627

Step 2 of 5: Calculate the estimated variance of errors, s^2e =0.125

Step 3 of 5: Calculate the estimated variance of slope, s^2b1=0.002

Step 4 of 5: Construct the 98% confidence interval for the slope= -0.409 , -0.079

Step 5 of 5: Construct the 80% confidence interval for the slope = -0.317 , -0.172
