A random sample of 11 workers produced the following data, where x is the years of employment, and y is the average number of minutes required to complete the morning duties. The data are presented below in the table of values. x y 5 49 8 42 10 41 12 39 15 37 16 34 19 30 22 25 25 24 27 22 28 16 What is the equation of the regression line? Select the correct answer below: ˆ y = 10.082 x + 54.2 ˆ y = − 1.267 x + 17.0 ˆ y = − 1.267 x + 54.2 ˆ y = 10.082 x + 17.0
