4) Use computer software to find the multiple regression equation. Can the equation be used for prediction? 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, 4)_ and SEX as the independent variables. For SEX, he used male-1 and female=2. WEIGHT CHEST LENGTH SEX 344 45.0 67.5 1 416 54.0 72.0 1 220 41.0 70.0 360 49.0 68.5 332 44.0 73.0 1 140 32.0 63.0 436 48.0 72.0 1 132 33.0 61.0 356 48.0 64.0 150 35.0 59.0 1 202 40.0 63.0 365 50.0 70.5 1 A) WEIGHT = 196 + 2.35CHEST + 3.40LENGTH + 25SEX; Yes, because the R2 is high. B) WEIGHT =-320+10.6CHEST + 7.3LENGTH-10.7SEX; Yes, because the P-value is high. C) WEIGHT =-442.6 + 12.1CHEST + 3.6LENGTH- 23.8SEX; Yes, because the adjusted R² is high. D) WEIGHT = 442.6+ 12.1CHEST + 4.2LENGTH– 21SEX; Yes, because the P-value is low. %3D |D %3D
when a regression is used as a method of predicting dependent variables from one or more independent variables. How are the independent variables different from each other yet related to the dependent variable?
Tire pressure (psi) and mileage (mpg) were recorded for a random sample of seven cars of thesame make and model. The extended data table (left) and fit model report (right) are based on aquadratic model  Write out the estimated quadratic polynomial regression model.
