The following data give the number of hours 10 students spent studying and their corresponding grades on their midterm exams
Step 1 of 5:
Calculate the sum of squared errors (SSE). Use the values b0=58.4077b0=58.4077 and b1=6.6860b1=6.6860 for the calculations. Round your answer to three decimal places.
Step 2 of 5:
Calculate the estimated variance of errors, s2ese2. Round your answer to three decimal places.
Step 3 of 5:
Calculate the estimated variance of slope, s2b1sb12. Round your answer to three decimal places.
Step 4 of 5:
Construct the 80% confidence interval for the slope. Round your answers to three decimal places.
Lower:
Upper:
Step 5 of 5:
Construct the 99% confidence interval for the slope. Round your answers to three decimal places.
Lower:
Upper:
Step 1 of 5: SSE =83.807
Step 2 of 5 : estimated variance of errors =10.476
Step 3 of 5: estimated variance of slope =0.264
Step 4 of 5:
lower =5.969
upper =7.403
Step 5 of 5:
lower =4.963
upper =8.409
