Chapter 1, Problem 1.39ACA
Sampling TV markets for a court case. A recent court case involved a claim of satellite television subscribers obtaining illegal access to local TV stations. The defendant (the satellite TV company) wanted to sample TV markets nationwide and determine the percentage of its subscribers in each sampled market who have illegal access to local TV stations. To do this, the defendant's expert witness drew a rectangular grid over the continental United States, with horizontal and vertical grid lines every .02 degrees of latitude and longitude, respectively. This created a total of 500 rows and 1,000 columns, or (500)(1,000) = 500,000 intersections. The plan was to randomly sample 900 intersection points and include the TV market at each intersection in the sample. Explain how you could use a random number generator to obtain a random sample of 900 intersections. Develop at least two plans: one that numbers the intersections from 1 to 500,000 prior to selection and another that selects the row and column of each sampled intersection (from the total of 500 rows and 1,000 columns).

You own the only pharmacy in the small town of Jackson City, which has 40,000 residents. You would like to get a sense of what the local demand is for seasonal allergy medicine so you can determine how many packages to keep in stock and what price to charge. You conduct a survey of four residents of Jackson City, asking them about the quantity of allergy medicine they would buy each allergy season at various prices. Their responses are shown in the accompanying table. Estimate and graph the demand for the entire town of Jackson City.

I submitted this question earlier and I understand how to add up the market demand for each individual but I don't understand how to estimate the entire market demand for Jackson city which has 40,000 residents including the individuals listed in the chart. If you could please answer this specifically I would appreciate it.
A rectangle is a four-sided figure that has two sets of parallel sides, so that we have two sides of one length and two sides
of another length; a square is just a special case of a rectangle in which all four sides are the same length. Therefore, the
procedure for calculating area is the same no matter whether we are dealing with a rectangle or a square.
The area of a rectangle is calculated as follows:
Area = base x height = b × h
In this formula, the base is the width of the rectangle and the height is simply how tall the rectangle Is. For example, if we
have a rectangle that is 20 centimeters wide and 10 centimeters tall, its area can be calculated as follows:
Area = 20 cm x 10 cm = 200 cm²
Note the superscript '2' In our answer; this is because we have multiplied centimeters by centimeters. In economics, we
are more likely to be dealing with quantities bought or sold and prices, so don't worry about it too much for our discussion.

Wine scores range from 0 to 100, with a score of 95 – 100 indicating a great wine, 90 – 94 indicating an outstanding wine, 85 – 89 indicating a very good wine, 80 – 84 indicating a good wine, 75 - 79 indicating a mediocre wine, and below 75 indicating that the wine is not recommended.

To understand their students' performance, the coaching center conducts the same test in both branches. A sample of 8 students have been selected from branches A and B respectively, and the following table shows data on their performance. Use appropriate non-parametric methods on the data to find out whether there is a statistically significant correlation between the ranks of the students’ performance of the two branches.?arrow_forwardRecently the European Community (EC) decided to lower its subsidies to makers of pasta. In deciding by what amount to reduce total subsidies, experiments were carried out for determining the possible reduction in exports, mainly to the United States, that would result from the subsidy reduction. Over a small range of values, economists wanted to test whether there is a positive correlation between level of subsidy and level of exports. A computer simulation of the economic variables involved in the pasta exports market was carried out. The results follow. Assuming that the simulation is an accurate description of reality and that the values obtained may be viewed as a random sample of the populations of possible outcomes, state whether you believe that a positive rank correlation exists between subsidy level and exports level over the short range of values studied Qarrow_forward
- A merchant who sells newspapers and magazines at the corner kiosk heard you manage the Times’ inventory and asks for your advice. She has a small, variable number of customers who daily purchase the Chicago Sun Times. In order to get the newspapers in time, she has to place an order for the next day’s newspapers before noon. She pays $0.50 for each newspaper and sells them for $1.50 each. She has kept detailed records of her past sales of the Chicago Sun Times and estimates that 10% of the time she sells 10 newspapers, 40% of the time she sells 11, 30% of the time she sells 12, and 20% of the time she sells 13. (a) What is the merchant’s marginal profit and marginal loss? (b) Determine how many Chicago Sun Times newspapers she should buy every day to maximize expected profits. (c) Calculate the merchant’s expected profits for the optimal order quantity. (d) The merchant has always purchased 13 newspapers, thinking that the best way to maximize profits was to always meet the demand.…arrow_forwardQuestion 13 Consider the Republic of Ashbury and apportion 250 seats among the five states using Webster's method.

- You can adjust the values in the accompanying table for fields with white backgrounds. Once you have selected a field, you can either enter a new value or adjust the existing value by selecting the arrows (+ to increase and to decrease). You can exit the entry field by hitting Enter (or Return) on your keyboard or by selecting a place elsewhere on the problem. To reset a field to its starting value, select the circular refresh arrow that appears next to the selected field. Experiment with entering different values in the editable fields. Observe what changes take place on the graph itself and also in the uneditable fields in the table. Don't worry about understanding the economics behind the question, just make sure you understand how to manipulate the values on the graph.
