c) Fit a simple linear regression model to the data for the prediction of the final score by the number of studying hours and interpret the slope. d) Find and interpret a 95% confidence interval for the slope of the regression line. e) Predict the final score for a student who studies 6.5 hours per week with a 95% confidence interval and interpret.

Step 1
The simple linear regression model can be written as: Final Score = β0 + β1 * Studying Hours + ε where β0 is the intercept, β1 is the slope, and ε is the error term. Using a statistical software, we can obtain the following regression equation: Final Score = Show more…

The following data give the number of hours 7 students spent studying and their corresponding grades on their midterm exams. Hours Studying | 1 | 2 | 2 | 3 | 3 | 4.5 | 5 Midterm Grades | 60 | 61 | 65 | 73 | 88 | 94 | 96 Step 5 of 5: Construct the 95 % confidence interval for the slope. Round your answers to three decimal places. Answer Lower endpoint: Upper endpoint:

the following data give the number of hours 5 students spent studying and their corresponding grades on their midterm exams. Hours Studying: 2 3 3 5 5 . Midterm Grades: 60 62 82 86 89. Construct the 80% confidence interval for the slope. Round your answer to three decimal places.

Use technology to find the 95% confidence interval. Remember that in a regression equation, ŷ is the estimated or predicted y-value and x is the value of the independent variable. Use this information to interpret the meaning of the confidence interval estimate for the true regression slope. Then use this interpretation to determine what conclusion can be reached about how long the accountant takes to count each additional unit.
