FDIC bank failures. The Federal Deposit InsuranceCorporation (FDIC) normally insures deposits of upto $100,000 in banks that are members of the FederalReserve System against losses due to bank failure or theft.Over the last 20 years, the average number of bank failuresper year among insured banks was 29 (FDIC Failed BankList, 2019). Assume that x, the number of bank failures peryear among insured banks, can be adequately character-ized by a Poisson probability distribution with mean 29.a. Find the expected value and standard deviation of x.b. In 2010, 157 banks failed. How far (in standard deviations)does x = 157 lie above the mean of the Poisson distribu-tion? That is, find the z-score for x = 157.c. In 2019, 4 banks failed. Find P(x ≤ 4).

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 80 stocks traded on the NYSE that day showed that 11 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly less than 0.3. You use a significance level of α=0.02α=0.02.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null fail…

Urgent Care is organized in to 4 department: Registration (Reg), Waiting (Wait), Treatment (Treat), and Payment & Check Out (PCO). For all patients who receive treatment at the Urgent Care, the expected time (in minutes) per patient needed in each of the departments: Reg. Wait. Treatment PCO 10 15 30 3 or 2 All patients enter and register at the registration cubicle. After registering, 10% of the patients walk out without waiting and seeing the physician for treatment. However, still they have to walk through the PCO & return the admissions slip. These patients need only 2 min at PCO (instead of 3 min). No waiting and treatment time for patients who walk out. Simulate the total time spent in the Urgent care for the first patient. Total time spent by Patient 1 at the Urgent Care is .

Chapter 5 In preparation for your discussion post, complete the following: • Research data on the U.S. uninsured population (https://aspe.hhs.gov/sites/default/files/private/pdf/265041/trends-in-the-us- uninsured.pdf B). • Choose one condition for your discussion post about an uninsured group. (For example, In 2019, 22% of Latine individuals under age 65 were uninsured, Figure 4 p.6). For your discussion board post include all of the following: 1. Suppose six individuals, within your criteria, are randomly selected. Show or explain your thinking for each problem. (Note: This is a binomial probability from Section 5.2, they either have insurance or they do not.) A. Let having insurance be a success. State the values of your p, q, and n for your chosen condition. Explain your thinking. (For my example, if 22% do not have insurance, then that is my q (failure) value, my p=0.78, q=0.22, n-6 (6 individuals are randomly selected in this problem). B.

To boost holiday sales, Ginsberg jewelry store is advertising the following promotion: “If more than five inches of snow fall in the first three days of the year (January 1 through January 3), all purchases made between Thanksgiving and Christmas are free!” Based on historical sales records as well as experience with past promotions, the store manager believes that the total holiday sales between Thanksgiving and Christmas could range anywhere between $200,000 and $400,000 but is unsure of anything more specific. Ginsberg has collected data on snowfall from December 16 to January 18 for the past several winters in the file Ginsberg. Construct a simulation model to assess potential refund amounts so that Ginsberg can evaluate the option of purchasing an insurance policy to cover potential losses. What is the probability that Ginsberg will have to refund sales? What is the average refund? Why is this a poor measure to use to assess risk? In the cases when snowfall exceeds 5…
