The table below gives the completion percentage and interception percentage for five randomly selected NFL quarterbacks. Based on this data,consider the equation of the regression line, y = bo + b₁x, for using the completion percentage to predict the interception percentage for an NFLquarterback. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it wouldnot be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.Completion Percentage 58 60 61 62 65Interception Percentage 5 4.5 4 3.5 3TableCopy DataStep 5 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.
