Homework Answers
1. Bring data in to excel sheet
2.Select both x and y variable and insert scatter plot chart. Select any data point in the excel and add trend line. In the format trend line option choose "Linear" and also select "Display an equation on chart"
Round answers to whole number:
Regression equation:
y = 4x + 53
(b) Prediction of student who studied for 6 hours
x = 6
y = 4x + 53
y = 4*(6) + 53 = 77
The predicted score is 77

The table below gives the number of hours ten randomly selected students spent studyling and their corresponding midterm exam grades. Using this data, consider the equation of the regression line, -bo +bix, for predicting the midterm exam grade that a student will earn based on the number of hours spent studying. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression...
