Question

The table below gives the n middle school students. Using this data, consider the equation of the regression line. bo t bi, for predict average for a middle school student based on the number of hours spent unsupervised each day may or may not be statistically significant for the data given. Remember, in practice, it would not be to make a umber of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected ing the overall grade . Keep in mind, the correlation coefficient appropriate to use the regression line on if the correlation coefficient is not statistically significant. Hours Unsupervised 0 05 1 2 4.5 5 6 Overall Grades 0 96 88 73 7 68 67 Table Copy Data Step 3 of 6: Substitute the values you found in steps 1 and 2 into the equation for the regression line to find the estimated linear model. According to this model, if the value of the independent variable is increased by one unit, then find the change in the dependent variable Tables Keypad How to enter your answer Previous step answers Previous Step Answers: Estimated slope bi-5.286 Estimated intercept bo 94.776
