Question

The following table compares the completion percentage and interception percentage of 5 NFL quarterbacks. Completion Percentage 57 59 61 65 65 Interception Percentage 4.8 4.7 4.5 3.1 1.1 Table

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

b1=−0.3727

b0=26.5238

SSE=2.842

s2e=0.947

Answer #1

The statistical software output for this problem is:

Hence,

Step - 3: Estimated variance of slope = (0.19601755)^{2}
= **0.038**
