ill leave a like thank you

Using the table below, you will go through all of the steps to calculate a Linear Regression and predict the scores of NEW people on one of the variables. X Y X2 Y2 XY 0 2 1 A 4 5 3 7 7 8 = - - 2 - Step one: Complete the table Question 1 Step two: Calculate the slope (b) b - )/ N] ' - ) IN) 0 -0.63 0.87 0 -0.74 0.77 Question 2 Step three: Calculate the means of X(Mx) and Y(MY) & O 2.89: 5.23 O 3.5: 6.7 O 3.25 : 6.1 O 3:5.2 Question 3 Step four: Calculate the intercept (a) a = My.bMx O 2.89 0 2.75 O 2.96 0 3.21 D Question 4 1 pt Step five: Using your equation for a straight line, the predicted value of Y for a new person who obtains a score of X = 8 would be (Plug in the values you just calculated for a & band X= 8. You are solving for Y!) Y = a + bx 8.56 10.23 O 9.23 09.05 Question 5 1 pts Step five CONTINUED: Using your equation for a straight line, the predicted value of Y for a new person who obtains a score of X = 2 would be (Plug in the values you just calculated for a & b and X= 2. You are solving for Y!) Y = a + bx O 3.56 05.16 4.43 0 4.57
