Question

The following data give the number of hours 5 students spent studying and their corresponding grades on their midterm exams.

Hours Studying	0	5	5	6	6
Midterm Grades	61	64	72	76	85

Step 1 of 6 : Calculate the sum of squared errors (SSE). Use the values b0=59.2382 and b1=2.8095 for the calculations. Round your answer to three decimal places.

Step 2 of 6: Calculate the estimated variance of errors, s^2e. Round your answer to three decimal places.

Step 3 of 6: Calculate the estimated variance of slope, s^2b1. Round your answer to three decimal places.

Step 4 of 6: Construct the 95% confidence interval for the slope. Round your answers to three decimal places.

Lower and upper endpoints.

Step 5 of 6: Construct the 98% confidence interval for the slope. Round your answers to three decimal places. Lower and upper endpoints

Step 6 of 6: Construct the 90% confidence interval for the slope. Round your answers to three decimal places. Lower and upper endpoints.
