Question

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

   Hours Studying	1	1	1	2	5
   Midterm Grades	85	86	91	96	100

   Step 4 of 5: Construct the 95% confidence interval for the slope. Round your answers to three decimal places.

   Step 5 of 5: Construct the 99% confidence interval for the slope. Round your answers to three decimal places.

2. I got help with steps 1-3 already, if you could show me how to do step four, I can figure out step 5 myself

   Step 1 of 5: Calculate the sum of squared errors (SSE). Use the values b0=85.2666 and b1=3.1667 for the calculations. Round your answer to three decimal places. 44.867

   Step 2 of 5: Calculate the estimated variance of errors, s2e. Round your answer to three decimal places.14.956

   Step 3 of 5: Calculate the estimated variance of slope, s2b1. Round your answer to three decimal places.1.246

Answer 1

Step 1 of 5: Calculate the sum of squared errors (SSE) =44.867

Step 2 of 5: Calculate the estimated variance of errors, s2e =14.956

Step 3 of 5: Calculate the estimated variance of slope, s2b1 =1.246

Step 4 of 5: Construct the 95% confidence interval for the slope = -0.386 , 6.719

Step 5 of 5: Construct the 99% confidence interval for the slope = -3.354 , 9.687
