Using data set I, answer the questions given below. DATA SET I Temperature and Energy Usage for a Residence (n = 24 months) Month Avg Temp (Fº) Usage (kWh) Month Avg Temp (Fº) Usage (kWh) 1 62 436 13 69 597 2 71 464 14 72 528 3 76 446 15 79 477 4 69 391 16 70 562 5 63 444 17 60 658 6 52 608 18 48 690 7 37 885 19 38 862 8 40 821 20 34 1008 9 39 830 21 25 840 10 35 750 22 38 867 11 45 617 23 48 606 12 54 598 24 53 657 picture Click here for the Excel Data Set I Choose the dependent variable (the response variable to be "explained") and the independent variable (the predictor or explanatory variable). (a-1) Dependent Variable Usage Avg Temp (a-2) Independent Variable Usage Avg Temp (b) Obtain the regression equation. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.) Y = X + (c) Calculate R2. R2 (d) Heteroscedasticity is a problem for this data set. Yes No
