Volume vs. Weight 45 Volume (m3) O 10 20 30 40 Weight (tonnes) Figure 1. Volume plotted over weight for the 10 sampled trucks.1. Based on Figure 1, answer the following: a. Do you think truck weight is linearly related to volume? Explain in 1-2 sentences. b. Does the data meet the assumption that the relationship between X and Y passes through the ongin? Y = a+bX b = NEXY- (EX)(EY) EY-bEx NEX2 - () X ) N Where, N = number of observations, or years X = a year index (decade) Y = population size for given census yearsVolume vs. Weight 45 40 35 Volume (m3) 10 20 30 40 Weight (tonnes) Figure 1.
