Sums of squares of residuals (2pts) An individual is using linear regression to predict the total points scored in a basketball game from the home team's offensive efficiency (HOffEff), the home team's defensive efficiency (HDefEff), the away team's offensive efficiency (AOffEff), and the away team's defensive efficiency (ADefEff). He assumes the model Pointsi = α + β1HOffEffi + β2HDefEffi + β3AOffEffi + β4ADefEffi + εi Which of the following is necessary for the regression model to minimize the sums of squares of the residuals? multiple choice The ε terms are all independent of each other The ε terms all have mean 0 The ε terms all have the same standard deviation The ε terms are all normally distributed All of the first four conditions must hold All of the first four conditions must hold, plus the model must be correctly specified Regression will always minimize the sum of squares of residuals Regression will never minimize the sum of squares of residuals Regression may or may not minimize the sum of squares of the residuals depending on the structure of the data

Calculate the effective radiation dosage in rems for a 71-kg person who is exposed to $2.3 \times 10^9$ particles of alpha radiation. Only 75% of the radiation is absorbed. Assume that each alpha particle has an energy of $5.3 \times 10^{-13}$ J and that the RBE of the alpha particles is 15. Note that the RBE is sometimes called quality factor (Q).
