Archаeоlоgists were interested in the effect оf toxic metаls on the heаlth of the upper-class citizens of ancient Rome. They conducted a study in which they analyzed the metal content of ancient Roman coins to determine the relative amounts of lead and gold. The table below shows the weight percent of gold and lead in the sampled coins. Weight % Gold Weight % Lead 0.3 0.17 0.31 0.19 0.28 0.21 0.32 0.22 0.34 0.28 0.29 0.26 0.33 0.32 0.26 0.17 0.3 0.19 0.27 0.19 0.27 0.17 A regression analysis of the data in the table gave the following results: Least Squares Regression Line: (wt% lead) = (-0.184 wt%) + 1.34(wt% gold) Correlation Coefficient r = 0.698 Standard Deviation About the Least Squares Line se = 0.038wt% Which of the following is true regarding predictions of Roman coin lead content based on the coin’s gold content? The least squares regression line for lead content vs. gold content will predict lead content with a tolerance of ± 0.038 weight%, but the linear relationship between lead content and gold content only accounts for about 49% of the variability in the coin lead content. The linear relationship between lead content and gold content accounts for about 70% of the variability in the coin lead content, but the least squares regression line will only predict lead content with a tolerance of ± 0.49 weight percent. The least squares regression line for lead content vs. gold content will predict lead content with a tolerance of ± 0.038 weight%, and the linear relationship between lead content and gold content accounts for about 70% of the variability in the coin lead content.
