Here is a bivariate data set. Find the regression equation for the response variable y. y 40 28.5 41.7 56.4 37.9 80.5 66.8 88.5 58.4 41 58.4 70.5 55.8 175.2 31.1 37.1 37.8 73.6 57.3 130.8 44.3 47.4 44.9 89.5 19.7 -2.2 38.8 52.8 38.8 72.2 15.9 18.1 36.6 120.1 56 117.7 54.6 54.6 regression equation: Enter the equation in slope-intercept form with parameters accurate to three decimal places. Please round all answers to 2 decimal places. Given the table below, use your calculator to find the Line of Best Fit x y 12.8 4.1 2.8 6.9 11.1 19.8 7.6 8.6 6.4 8.7 19.3 21.5 17.8 21.8 y = Here are the scatter plots for two sets of bivariate data with the same response variable. The first compares the variables x &y. The second compares the variables w & y 000 900 Which explanatory variable has a stronger relationship with the response variable y? O The first variable (x) has a stronger relationship with the response variable y. O The second variable (w) has a stronger relationship with the response variable y. A researcher studied the eyesight of people at different ages. She calculated a vision score for each person in the study and plotted the data on the graph below. Vision Score 110 108 106 104 102 100 98 EYESIGHT STUDY . 0 20 25 30 35 40 45 50 55 60 65 70 75 Age (years) The researcher used the line y = -0.1x + 110 to model the data. When she substituted the value x = 65 into this equation, what did the result tell her? O The exact value for the vision score of a 65-year-old O the predicted value for the vision score of a 65-year-old O the minimum possible value for the vision score of a 65-year-old O the maximum possible value for the vision score of a 65-year-old
