My homework question is: A STAT 200 instructor believes that the average quiz score is a good predictor of final exam score. A random sample of 10 students produced the following data where x is the average quiz score and y is the final exam score.

x 80 95 50 60 100 55 85 70 75 85

y 70 96 50 63 96 60 83 60 77 87

I need to find an equation of the least squares regression line and round the slope and y-intercept value to two decimal places. I also find what the predicted final exam score is if the average quiz score is 65. Then I need to answer "Which predicted final exam score that you calculated for (b) and (c) do you think is closer to the true final exam score and why?"

I am very confused please help
