Step 1: find the estimated slopeStep 2: find the estimated y intercept. Round to three decimal places.Step3: find the estimated value of y when x=4.5. Round to three decimal places.Step 4: 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 variabley^.Step 5: Determine if the statement "All points predicted by the linear model fall on the same line" is true or false.Step 6: fund the value of coefficient of determination ^

The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, y = bo + bix, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. 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 line to make a prediction if the correlation coefficient is not statistically significant.
