The answer of the question “How was the sample selected?”
Answer to Problem 1CS
Solution: The required answer will be the sample is who completes the survey among 2879 residents.
Explanation of Solution
In the provided study, the sample was collected after calling 2879 residents. Therefore, the required answer that is given by “The Pew Research Center” will be the resident who completes the survey is considered as the sample.
The answer of the question “How large was the sample?”
Answer to Problem 1CS
Solution: The required answer is 1000 residents.
Explanation of Solution
In the provided study, the research question is asked to 1000 residents. So, the required answer will be 1000 residents.
The answer of the question “What was the response rate?”
Answer to Problem 1CS
Solution: The required answer will be that the response rate is 42%.
Explanation of Solution
The response rate for any study can be obtained if the number of respondents who answer the research question is known. In the provided study, the nonresponse rate is 58%. So, the response rate is calculated as
The answer of the question “How were the subjects contacted?”
Answer to Problem 1CS
Solution: The required answer is that the subjects are contacted through telephone.
Explanation of Solution
In the provided study, the subjects of the study are contacted through the telephone interview. Therefore, the required answer for the particular question would be that the subjects are contacted through telephone.
The answer of the question “What were the exact questions asked?”
Answer to Problem 1CS
Solution: It is not possible to answer the provided question.

- Note: The purpose of this problem below is to use computational techniques (Excelspreadsheet, Matlab, R, Python, etc.) and code the dynamic programming ideas seen inclass. Please provide the numerical answer to the questions as well as a sample of yourwork (spreadsheet, code file, etc.).We consider an N-period binomial model with the following properties: N = 60, thecurrent stock price is S0 = 1000; on each period, the stock price increases by 0.5% whenit moves up and decreases by 0.3% when it moves down. The annual interest rate on themoney market is 5%. (Notice that this model is a CRR model, which means that thebinomial tree is recombining.)(a) Find the price at time t0 = 0 of a (European) call option with strike price K = 1040and maturity T = 1 year.(b) Find the price at time t0 = 0 of a (European) put option with strike price K = 1040and maturity T = 1 year.(c) We consider now, that you are at time t5 (i.e. after 5 periods, which represents 1month later).
