A study examined the relationship between population growth and change in unemployment rate (y) in a sample of 100 U.S. cities. Based on the collected data, the least squares regression line is ? = 5.21 + 11.28x, where x is the annual population growth rate. Assume all regression conditions are met. Based only on the given information, what can be said about the correlation between population growth and change in unemployment rate? O The correlation coefficient is 5.21. O The correlation coefficient is 0. O The correlation coefficient is 0.892 O The correlation coefficient is positive but we cannot say what the exact value is. It is impossible to say anything about the correlation coefficient from the information given. S
