We want to assess the linear relationship between tardiness and gpa. Of 43 students, we see an average absence number of 3.58 and an average GPA of 2.93 with standard deviations 2.59 and 0.64. The correlation coefficient R=-0.784. The scatter plot of our data is shown below: : 6 8 10 1. Sketch your guess for the line of best fit on the scatter plot (dashed please!). 2. Calculate the least squares estimate of 31. 3. Calculate the least squares estimate of Bo. 4. Write the equation of the line of best fit and plot it in a solid line on the scatter plot. 5. What is the residual of the point (2,3.59)? (the difference between the real value and the least squares prediction) 6. Using the following output, show the calculation for the t-value for both 30 and 3₁. 7. Can we say, with 95% confidence, that 3₁ #0? Why or why not?
