Use computer software to obtain the regression equation. Use the estimated equation to find the predicted value. A wildlife analyst gathered the data in the table to develop an equation to predict the weights of bears. He used WEIGHT as the dependent variable and CHEST, LENGTH, and SEX as the independent variables. For SEX, he used male = 1 and female = 2. He took his equation "to the forest" and found a male bear whose chest measured 70.3 inches and who was 64.0 inches long. WEIGHT CHEST LENGTH SEX 3-4 150 675 416 540 72.0 220 410 700 IN 380 490 685 332 440 73.0 1:40 320 630 436 480 720 132 33.0 610 356 480 640 UNONNEI 150 350 590 202 400 630 365 500 705 Data in R format: bear firm = data. frame( WEIGHT-c( 344, 416, 220, 360, 332, 140, 436, 132, 356, 150, 202, 365), CHEST-c(45, 54. 41, 49, 44, 32, 48, 33, 48, 35, 40, 50).
