Question

If the following data were transformed and points with the coordinates (x,log(y)) were plotted, what points would be plotted? Round log(y) to three decimal places.X Y1 172 1183 826

Answer 1

SOLUTION

From the table

At x = 1 and y = 17 ⇒ (x,log(y)), becomes

$(1,log(17)=(1,1.2304489)=(1,1.230)$

At x = 2 and y = 118 ⇒ (x,log(y)), becomes

$(2,log(118)=(2,2.071882007)=(2,2.072)$

At x = 3 and y = 826 ⇒ (x,log(y)), becomes

$(3,log(826)=(3,2.91698004)=(3,2.917)$

Hence the answer is

(1, 1.230)

(2, 2.072)

(3, 2.917)
