US GOVERNMENT
How do the U.S. government's efforts to build good relations with other countries promote the public good? Do you think U.S. foreign policy in general has promoted the public good?
STATISTICS
(a) identify the claim and state $H_0$ and $H_a$ (b) find the critical value and identify the rejection region, (c) find the test statistic F, (d) decide whether to reject or fail to reject the null hypothesis, and (e) interpret the decision in the context of the original claim. Assume the samples are random and independent, and the populations are normally distributed. An employment information service claims that the standard deviation o[ the annual salaries for public relations managers is less in Florida than in Louisiana. You select a sample of public relations managers from each state. The results of each survey are shown. At $\alpha=0.05$, can you support the service's claim? Public relations managers in Louisiana $$ \begin{array}{l} s_{1}=\$ 42,000 \\ n_{1}=24 \end{array} $$ Public relations managers in Florida $$ \begin{array}{l} s_{2}=\$ 36,300 \\ n_{2}=28 \end{array} $$

PREALGEBRA
Weakly salaries at the public relations department in a company are $1200,$1000, $900,$2000, and $1500. Suppose a new employee is added and that her salary does not change the median. What is the weekly salary of the new employee?
DISCRETE MATH
Let A = {v, w, x, y, z}. Determine the number of relations on A that are (a) reflexive and symmetric; (b) equivalence relations; (c) reflexive and symmetric but not transitive; (d) equivalence relations that determine exactly two equivalence classes; (e) equivalence relations where w $\in$ [x]; (f) equivalence relations where v, w $\in$ [x]; (g) equivalence relations where w $\in$ [x] and y $\in$ [z]; and (h) equivalence relations where w $\in$ [x], y $\in$ [z], and [x] $\neq$ [z].
PRECALCULUS
Keisha says that all functions are relations but not all relations are functions. Kevin says that all relations are functions but not all functions are relations. Who is correct and why?
DISCRETE MATH
Let X = {0, 1}. (a) List (as subsets of $X \times X)$ all possible relations on X. (b) Which of the relations in part (a) are equivalence relations?
CALCULUS
Suppose that out of 19 members of a club, two committees are to be formed. A nominating committee is to consist of 7 members, and a public relations committee is to consist of 5 members. No one can be on both committees. (a) Calculate the number of ways that the two committees can be formed, assuming that the nominating committee is formed first. (b) Calculate the number of ways that the two committees can be formed, assuming that the public relations committee is formed first. Verify that this answer is the same as that of part (a). (c) Suppose the 7 members of the nominating committee wear red T-shirts, the 5 members of the public relations committee wear yellow T-shirts, and the remaining members of the club wear white T-shirts. A photographer lines up the members of the club to take a picture, but the picture is so blurry that people wearing the same color T-shirt are indistinguishable. In how many distinguishable ways can the club members line up? Explain why this answer is the same as the answers to parts (a) and (b).
DISCRETE MATH
Let A be a set with eight elements. a. How many relations are there on A? b. How many relations on A are reflexive? c. How many relations on A are symmetric? d. How many relations on A are both reflexive and symmetric?
PRECALCULUS
