Question

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

Completion Percentage	55	59	60	60	62
Interception Percentage	4.5	4.2	3.5	2.9	1.4

Step 1 of 5: Calculate the sum of squared errors (SSE). Use the values b0=26.9386 and b1=−0.3993 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.
