Imagine you are driving home from vacation in Oklahoma. You have 1/4 tank of gas left, having driven 200 miles on 3/4 of a tank. a. Find the UNIT RATE - how far can your car go on one full tank of gas?

b. You still have 80 miles to drive in order to get home. Using your unit rate, will you be able to make it without stopping on your last 1/4 tank of gas?

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). =
