The accompanying data show the South African population versus expenditure on new construction works by the public sector. Data was obtained from Statistics South Africa for the period between 2014 to 2017. Year S.A. Population (per million) (x) Expenditure on new construction (per million) (y) 2014 44.12 17.38 2015 44.68 19.20 2016 45.25 20.25 2017 45.80 36.49 Σx= 179.85 Σy= 93.32 Σxy = 4212.2161 Σx2 = 8088.0793 Σy2 = 2412.2870 Using the information above, determine which of the following statements are correct? A. slope=-442.832 which measures the change in Y per unit change in X. B. slope=10.3678, which measures the change in Y per unit change in X. C. slope=0.0694, which is a measure of the strength of the linear relationship D. slope=10.3462, which is a measure of the strength of the linear relationship
