Life Expectancies A random sample of nonindustrialized countries was selected, and the life expectancy in years is listed for both men and women. Men 60.2, 43.9, 59.8, 66.1, 68.4, 64.8 Women 60, 43.8, 56.6, 72.7, 63.5, 66 The correlation coefficient for the data is r= .914 and a= .05. Should regression analysis be done? The regression analysis should not be done or The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places, if necessary y'= a+bx a= b= Find women's life expectancy in a country where men's life expectancy = 62 years. Round your answer to at least three decimal places. Women's life expectancy is years.
