A painter is preparing an estimate to paint a building. To approximate the
building's height, he stands so that the tip of his
shadow coincides with that of the building. The
painter uses the measurements shown in the figure.

1. The painter's partner is standing in the sun.
She is 62 inches tall. How long is her shadow?

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
