Essay

Two similar cities tried out two programs, P and Q, to cut down on the use of tobacco. They tested the programs with a total of 2000 junior high students. $$\begin{array} { | l | l | l | l | } \hline & \begin{array} { c } \text { Students used } \\\text { tobacco less or same }\end{array} & \begin{array} { c } \text { Students used } \\\text { tobacco more }\end{array} & \\\hline \text { Tobacco program P } & & & \\\hline \text { Tobacco program Q } & & & \\\hline & & & 2000 \\\hline\end{array}$$
A) 60% of the 2000 students were in program P. Enter that number of students in the appropriate place in the contingency table.
B) 30% of all the students used tobacco more. Enter that number of students in the appropriate place in the table.
