Question 1

Use the equation f = 131.8/ - 947.5 to i. find the output f when the input / = 5.2. Answer: (Round the answer to 2 decimal places) ii. find the input / when the output f = -552.7 . Answer: (Round the answer to 2 decimal places)The linear regression equation for a data set is y = 4.1 + 1.6x. The actual value at = 2 is 1.1. What is the residual value at x=27 residual: | | Assume that variables x and gy have a significant correltation, and that the line of best fit has been calculated as = 1.4z + 4. One observation is (4,11.9). What is the predicted value of y for the value z = 47 | What is the residual for the value r = 47 What is the best interpretation for the residual? ' The value 11,9 is above the average value for y when = = 4. ' The value 4 is above the average value for iy when y = 11.9 "1 The value 11.9 is below the average value for z when y = 11.9 ' The value 11,9 is below the average value for y when z = 4
