In the following study a researcher was interested in whether infant mortality was related to the level of pollution in the city. For this purpose he collected the following data for n = 20 heavily populated localities. For each locality, an index (X) measuring the average daily level of pollution was determined along with the average infant mortality rate, (Y) over the past ten years. The data is tabulated below: 2. Locality (i) Pollution Index (X) Infant Mortality Rate 3.32 2.41 KY) Locality (i) Pollution Index (X) Infant Mortality Rate 5.09 4.84 KY) 6. 9. 10 3 5 4 23.6 21.9 23.2 | 12.7 | 14.8 26.3 17.8 27.2 17.5 6.4 3.85 5.59 5.8 4.65 5.98 5.75 3.17 2.68 19 20 18 17 13 14 15 16 11 12 23.9 18.9 | 20.1 18.4 2.73 5.74 4.16 | 4.96 18.6 28.2 21.3 18.7 18.3 24 5.22 4.74 4.44 6.61 Estimate the parameters of the least squares line. Determine 95% confidence limits for the parameters of the least squares line. Plot a graph of the data showing the least squares line. What conclusions would you make from this analysis? Predict the infant mortality rate in the city where the pollution index was 10.7. Compute 95 % prediction limits for this mortality rate. A. B. C. D. E.
