A) Explain the role of prices in allocating scarce resources in a market economy.

B) Discuss the view that that the use of maximum and minimum price controls only serve to distort markets and bring about a misallocation of resources.  

Government surveillance is said to address threats to public safety and national security. In addition, private sector organizations often claim that the collection and analysis of “big data” leads to highly efficient business practices and better service to customers. Yet, the methods and scope of surveillance in the 21st century generate difficult questions for policy makers. Suppose it is your task to find an acceptable balance between, on the one hand, the use of surveillance to enhance public safety and national security and, on the other hand, society’s interest in guaranteeing personal privacy. To which fields of academic or professional activity will you turn for perspective and guidance? How, in your view, do these various fields of academic or professional endeavor inform policy debate about surveillance in a democratic society? Carefully explain your responses. [note: the purpose of this question is to cause you to think in interdisciplinary ways about the matters of “surveillance society” and person privacy

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities.

Do you try to pad an insurance claim to cover your deductible? About 44% of all U.S. adults will try to pad their insurance claims! Suppose that you are the director of an insurance adjustment office. Your office has just received 122 insurance claims to be processed in the next few days. Find the following probabilities. (Round your answers to four decimal places.)

(a) half or more of the claims have been padded


(b) fewer than 45 of the claims have been padded


(c) from 40 to 64 of the claims have been padded


(d) more than 80 of the claims have not been padded

2. In class, we learned that the running time of Karatsuba’s algorithm can be expressed as the recurrence T (n) = 3T (n/2) + n. We then used the substitution method to solve the recurrence.

   When using the substitution method, it seems difficult to make a guess about the upper bound on the running time. However, if we use the recursion tree method, it would be a lot easier.

   In this question, you are asked to solve this recurrence using the recursion tree ap- proach, which can be further used to help us make the guess (you are not required to explain how to make use of your result to make the guess; only show your work using the recursion tree). You can assume that T(1) = 1 and that n is a power of 2 for convenience. Give your solution using big-Oh notation.

Below are two hypothesis tests for claims made about the proportion. These are both very controversial having to do actual election results in America. In some cases I rounded numbers off for convenience. This round off is negligible and does not change conclusions of the hypothesis test. They are similar. Do either one for test credit, and both for (+5) extra credit. If you do both I will count the best one for test credit, and the other for extra credit) (+12)

In the year 2000 George Bush defeated Al Gore in a very close election for President. A very important state was Florida. There was a very big problem with the vote count and ballot in Palm Beach County. There, many votes were cast for Pat Buchanan (a very unpopular candidate in the entire State). Only 17,356 of 5,930,820 voted for Buchanan in the State of Florida giving a population proportion of .0029. Supporters of Al Gore said that the 3407 of 462,000 votes for Buchanan in Palm Beach County was too high forming a proportion for this county that was significantly greater than .0029. They claimed there must have been some kind of error in the count of the ballot. Test the claim that the proportion is greater than .0029 at a statistical level of significance of .01. Show your hypothesis test and state your conclusion. Also, tell what you think about the results.( Below is the ballot used)

Conclusion:

B. ..."Democracy failed in Georgia," Abrams said of the contest, which was marred by allegations of voter roll purging and suppression largely affecting African Americans. "This time, the mistakes clearly altered the outcome." This Quote was taken from Stacy Abrams. She was defeated by Brian Kemp in a race for Governor of Georgia in 2018. Her statement was based on a claim that the proportion of African American voters whose voter registration application where either on hold, or were not allowed to vote, was far too high. The population proportion of African American voters in this state is 32%. This sample of 53,000 “voters” whose votes were not counted, or were not allowed to vote, revealed approximately 37,100 were African Americans (this is 70%). Defenders of the Secretary Of State (who was, in fact, her opponent Brian Kemp), said their registrations were in error. In fact, this was true in some cases, were the applicant moved and their address were wrong, or things like a missing suffix (like Junior (Jr.)) was left off. Suppose it was found that of the 70% of African Americans whose votes were not counted, Kemp found legitimate reasons for about 20%.

Suppose Kemp is given the benefit of doubt, and we consider the sample of people who were not allowed to vote, or whose vote was not counted, to be 26500 African Americans from the 53,000. (that is, a sample proportion of .50)

Given the population proportion of African Americans in Georgia is 32%, test the claim that 26500 African Americans, of 53000 people whose vote was not counted or were not allowed to vote was too high. In fact, it is, to Quote Stacy Abrams “Outrageous”, at the 1% level of significance. Give the hypothesis test as well as what you think about this result.

Gallup recently conducted a surveyabout the proportion of Americans who use e-cigarettes (vape). The following example is based on hypothetical data that is meant to be similar to the data collected by Gallup.

The following table considers survey data about annual household income and whether or not a person vapes.

Problem 1. Based on recent data, about 28% of Americans earn less than $35,000 annually, about 42% of Americans earn between $35,000 and $99,999 annually, and about 30% of Americans earn more than $100,000. Does it appear that the sample is representativeof the population? In other words, does it appear that the total people in each income category matches the appropriate proportion? Conduct a chi-square goodness of fit test at the 5% significance level by completing the following steps:

a. State the null and alternative hypotheses in words.

b. Compute the expected frequencies for each of the three category. Be sure to show your work.

c. Compute the test statistic using the observed frequencies from the table and the expected
