DETERMINE THE EQUATIONS OF THE REGRESSION

Linear Regression Application, Interpolation and Extrapolation Use the data and story to answer the following questions The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. T 11.6 8.6 6.6 3.9 2.3 2.2 2.6 0.4 14.1 11.6 9.5 7.4 5.7 6 6 4.6 = thousands of automatic weapons y = murders per 100,000 residents Use your calculator to determine the equation of the regression line. (Round to 2 decimal places) Determine the regression equation in y = ax + b form and write it below. A) How many murders per 100,000 residents can be expected in a state with 8.3 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 4.2 thousand automatic weapons? Answer = Round to 3 decimal places.QUESTION 8 Which of the following statements is true? O a. In the simple linear regression model given by: y = beta0 + beta1 x + e, the variable y is the regressor. O b. In the simple linear regression model given by: y = beta0 + beta1 x + e, the variable y is the independent variable. O . In the simple linear regression model given by: y = beta0 + beta1 x + e, the parameter beta1 is the slope. O d. In the simple linear regression model given by: y = beta0 + beta1 x + e, the variable e is the coefficient of determination. O . In the simple linear regression model given by: y = beta0 + beta1 x + e, the parameter beta1 is the intercept
