In a study of the causes of bearing wear, a machine was run 24 times, with various loads (denoted x1), oil viscosities (x2), and ambient temperatures (x3). The wear, denoted y, was modeled as y = β0 + β1x1 + β2x2 + β3x3 + ε. When this model was fit to the data, the sum of squares for error was SSE = 9.37. Then the reduced model y = β0 + β1x1 + β2x2 + β3x3 was fit, and the sum of squares for error was SSE = 27.49. Is it reasonable to use the reduced model, rather than the model containing all the interactions, to predict wear? Explain.

Find the least-squares equation for these data (rounded to three digits after the decimal).ŷ = + x (c) In the data for parts (a) and (b), did we simply exchange the x and y values of each data pair?
YesNo
(d) Solve your answer from part (a) for x (rounded to three digits after the decimal).x = + y Do you get the least-squares equation of part (b) with the symbols x and yexchanged?
YesNo
(e) In general, suppose we have the least-squares equation y = a + bx for a set of data pairs (x, y). If we solve this equation for x, will we necessarily get the least-squares equation for the set of data pairs (y, x), (with x and y exchanged)? Explain using parts (a) through (d).
In general, switching x and y values produces the…

This implies that if the height is increased by 1 inch, the weight is expected to: A. decrease by 1 pound B. increase by 1 pound C. increase by 5 pounds D. increase by 24 poundsarrow_forwardEach of 25 teenage girls with one brother was asked to provide her own height (y), in inches, and the height (x), in inches, of her brother. The scatterplot below displays the results. Only 22 of the 25 pairs are distinguishable because some of the (x,y) pairs were the same. The equation of the least-squares regression line is ŷ = 35.1 + 0.427x.*Girls are on the y-axis and brothers are on the x-axis* a.) Draw the least-squares regression line on the scatterplot above. b.) One brother’s height was x = 67 inches and his sister’s height was y = 61 inches.
