Consider two variables: one denotes whether a person truly has a disease (D) or not (D) and the otherdenotes whether a person tests positively for the disease (Pos) or not (Neg). Use the contingency table toanswer the questions.PosNegD532(a) Calculate P(Posn D).(b) Calculate P(Negu D).(c) Calculate P(Pos|D) (this is called the sensitivity).(d) Calculate P(Neg|D) (this is called the specificity).Dº4455

Several states have argued that the 65-mph speed limit has no justification and have refused to enforce it. The federal Department of Transportation (DOT) believes that the 65-mph limit saves lives. To illustrate its contention, the department regressed the number of traffic fatalities (Y) last year in a state on the state’s population (X1), the number of days of snow cover (X2), and the average speed of all cars (X3). The results are shown below. Table 10: Model Summary Model R R Square Adjusted R Square Std. Error of the Estimate 1 .821 a .780 .613 3.258 a.
