Question

The following table compares the completion percentage and interception percentage of 5 NFL quarterbacks.

Completion Percentage	55	58	58	60	64
Interception Percentage	4.5	4.5	4	3.5	3

Step 1 of 5: Calculate the sum of squared errors (SSE). Use the values b0=14.6262 and b1=−0.1818 for the calculations. Round your answer to three decimal places.

Step 2 of 5: Calculate the estimated variance of errors, se2. 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 99% confidence interval for the slope. Round your answers to three decimal places.

Step 5 of 5: Construct the 98% confidence interval for the slope. Round your answers to three decimal places.

Answer 1

from given data:

Step 1 of 5: Calculate the sum of squared errors (SSE) =0.245

Step 2 of 5: Calculate the estimated variance of errors, se2. =0.082

places.

Step 3 of 5: Calculate the estimated variance of slope, s2b1.=0.002

Step 4 of 5: Construct the 99% confidence interval for the slope=-0.434 ;0.070

Step 5 of 5: Construct the 98% confidence interval for the slope =-0.378 ; 0.014
