Artificial Intelligence Lili and Jojo received an assignment from the West Jakarta Mayor to record the number of family heads and the number of residents in each complex in West Jakarta City. When noting that Lili realized that instead of counting them one by one, she could use the data to predict the population in a complex based on the number of family heads or vice versa. Help Lili and Jojo to create predictive models using linear regression methods. The following is the data on the number of family heads and the population of each complex that Lili and Jojo recorded: No. 1 Number of Family Heads 15 20 28 2 3 4 39 5 30 6 43 7 12 8 45 46 9 Total Population 80 90 150 250 180 353 42 400 405 67 300 420 130 380 20 260 200 100 40 210 10 11 12 13 13 41 50 24 43 14 15 16 40 17 18 33 21 11 35 19 20 a. Using the partial derivatives = 0 method, determine the linear regression equation from the data above! b. If in the next complex Lili and Jojo count there are 25 heads of families, what is the predicted number of inhabitants in the complex
