Step 1 of 5: Calculate the sum of squared errors (SSE). Use the values b0=63.0344 and b1=5.5690 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.
The statistical software output for this problem is :
1)
SSE = 9.690
2)
S2e = 3.230
3)
S2b = 0.098
4)
