You were given a dataset that includes 100 datapoints for expenses in Canadian dollars and waste in kilo grams. Based on the data you were able to calculate the following: The variance of the expenses = 78515151.52 The variance of the waste amount 14602.38, The R squared = 0.372460641, Intercept = cS 34046.3765, Total waste amount = 54420 kg ion Then the slope of the regression line is (approximately) O a 44,75124 O b. 54.420 Oc 5840 Od. 34.04637
