(i) Calculate the value of the correlation coefficient. (Round your answer to four decimal places.) r= (ii) Interpret the value of the correlation coefficient. READ AND COMPLETE THE FOLLOWING STATEMENT. If we consider a weak association one where (Irl 0.8) , then there is a Select @ , select @ association between pollution and cost of medical care per person. (c) Write a few sentences summarizing what the scatterplot and value of the correlation coefficient tell you about the relationship between pollution and medical cost per person over age 65. READ AND COMPLETE THE FOLLOWING STATEMENT. The scatterplot shows a select @ association between cost of medical care per person and pollution level. The sign of the correlation coefficient supports the Select [ association between the variables. Both the scatterplot and correlation coefficient tell us that people over the age of 65 living in more polluted areas tend to have select E) medical costs
