A researcher wants to know if the gestation period of an animal can be used to predict life expectancy. She collects the following data: - Draw a scatter plot - Use the formulas to compute the linear correlation coefficient between gestation period and life expectancy. - Use the formulas to find the least-squares regression line - Would it be reasonable to use the equation to predict the life expectancy if the gestation period are 10, 50, or 200 days, respectively...

Data from the 1993 World Almanac and Book of Facts were used to predict the life expectancy for men in a country from the life expectancy of women in that country. The resulting regression equation was Yˆ = 9.32 + 0.79(X). Using the regression equation, what would you predict...
