A 2018 Pew Research Center report asked people who got their news from television which television sector they relied on primarily for their news: local TV, network TV, or cable TV. The results were used to generate the data in the table below.

a. Include the row totals, column totals, and the grand total in the table. Show the complete table with the totals.

b. Determine whether, for this sample, choice of cable TV is independent of being male. Explain your answer in the context of this problem.

	Local TV	Network TV	Cable TV	Total
Men	66	48	58
Women	82	54	56

Probabilities for three states of the economy and probabilities for the returns on a particular stock in each state are shown in the table below.

$$\begin{array}{lclc}\hline &&&\textbf{Probability of Stock}\\ &\textbf{Probability of}&\textbf{~~~~~~~Stock}&\textbf{Performance in Given}\\ \textbf{State of Economy}&\textbf{Economic State}&\textbf{Performance}&\textbf{Economic State}\\\hline \text{Good}&.3&\text{Good}&.6\\ &&\text{Neutral}&.3\\ &&\text{Poor}&.1\\\hline \text{Neutral}&.5&\text{Good}&.4\\ &&\text{Neutral}&.3\\ &&\text{Poor}&.3\\\hline \text{Poor}&.2&\text{Good}&.2\\ &&\text{Neutral}&.3\\ &&\text{Poor}&.5\\\hline \end{array}$$

What is the probability that the economy will be neutral and the stock will experience poor performance?

Do you think the Assyrians’ almost exclusive reliance on military power was a good strategy for creating their empire? Why or why not?

It costs a company $30,000 to begin production of a good, plus$3 for every unit of the good produced. Let x be the number of units produced by the company.

(a) Find a formula for $C(x)$, the total cost for the production of $x$ units of the good.

(b) Find a formula for the company's average cost per unit, $a(x)$.

(c) Graph $y=a(x)$ for $0<x \leq 50,000,0 \leq y \leq 10$. Label the horizontal asymptote.

(d) Explain in economic terms why the graph of $a$ has the long-run behavior that it does.

(e) Explain in economic terms why the graph of $a$ has the vertical asymptote that it does.

(f) Find a formula for $a^{-1}(y)$. Give an economic interpretation of $a^{-1}(y)$.

(g) The company makes a profit if the average cost of its good is less than $\$ 5$ per unit. Find the minimum number of units the company can produce and make a profit.

Some parents let their infants go to sleep with a bottle of apple juice. Discuss, with reasons, whether this is a good or a bad idea.

At f = 100 MHz, show that silver $\left(\sigma=6.1 \times 10^{7} \mathrm{S} / \mathrm{m}, \mu_{r}=1, \varepsilon_{r}=1\right)$ is a good conductor, while rubber $\left(\sigma=10^{-15} \mathrm{S} / \mathrm{m}, \mu_{r}=1, \varepsilon_{r}=3.1\right)$ is a good insulator.

Use given problem to get good upper and lower bounds for the sum of the first 10 million terms of the harmonic series.

Aqueous $\operatorname{tin}(\mathrm{II})$ ion, $\mathrm{Sn}^{2+}(\mathrm{aq})$, is a good reducing agent. Use data from Appendix D to determine whether $\mathrm{Sn}^{2+}(\mathrm{aq})$ is a sufficiently good reducing agent to reduce
(d) $\mathrm{Pb}^{2+}(\mathrm{aq})$ to $\mathrm{Pb}(\mathrm{s})$.

A firm is a natural monopoly if ________. A. it can produce the good at a price below its competitor’s price B. it can produce a larger quantity of the good than other firms could C. the government grants it a public franchise or patent D. it can satisfy the market demand at a lower average total cost than other firms can

In a slow year, Deutsche Burgers will produce 2 million hamburgers at a total cost of $3.5 million. In a good year, it can produce 4 million hamburgers a total cost of$3.5 million. In a good year, it can produce 4 million hamburgers at a total cost of $4.5 million. What are the fixed and variable costs of hamburger production?

Your friend defines a right angle as an angle that is greater than an acute angle. Use a biconditional to show that this is not a good definition.

A random sample of individuals were rated as to their standing posture. In addition, the numbers of days of back pain each had experienced during the past year were also recorded. Surprisingly to the researcher these data indicated a positive correlation between good posture and number of days of back pain. Does this indicate that good posture causes back pain?

Fill in the blank with the term that best complete the sentence. A good scientific ____ can be repeated by someone else, and the same results will be found.

Aqueous tin(II) ion, $\mathrm{Sn}^{2+}(\mathrm{aq})$, is a good reducing agent. Use data from Appendix $D$ to determine whether $\mathrm{Sn}^{2+}(\mathrm{aq})$ is a sufficiently good reducing agent to reduce
