Refer to the results from the 150 subjects given below.

$$\begin{array} {c c c } &{ \text { Spent the Money } } & { \text { Kept the Money } } \\ \hline \text{Women Given a Single 100-Yuan Bill}&60 & { 15 } \\ \hline \text{Women Given 100 Yuan in Smaller Bills}&68 & { 7 } \\ \hline \end{array}$$

Find the probability that if 1 of the 150 subjects is randomly selected, the result is a woman who spent the money or was given a single 100-yuan bill.

The money raised and spent (both in millions of U.S. dollars) by all congressional campaigns for 8 recent 2 -year periods are shown in the table. The data can be modeled by the regression equation

$\hat{y}$=0.943 x+21.541.

Use the data to find the

a) coefficient of determination and interpret the result,

b) standard error of estimate $s_e$ and interpret the result.

This exercise comes in two parts. Read Part I and answer (a) and (b), then read Part II and answer (c) and (d). Part 1. A catering company contracts to provide catering services to three schools: Alexdale, with 617 students BromviUe, with 1,292 students, and Canley, with 981 students. The 30 food-service workers employed by the catering company are apportioned among the schools based on student enrollments. (a) Find the standard divisor,rounded lo the nearest integer. (b) Find the apportionment of the 30 workers to the three schools under Hamilton's method. Part 11. The catering company gets a contract to service one additional school-Dillwood, with 885 students To account for the additional students, the company hires 9 additional food-service workers. [885 students represent approximately 9 workers based on the standard divisor found m(a).] (c) Find the apportionment of the 39 workers to the four schools under Hamilton's method. (d) Which paradox is illustrated by the results of (b) and (c) ? Explain.
