8. Individual Problems 20-4 Suppose that every driver faces a 4% probability of an automobile accident every year. An accident will, on average, cost each driver $5,000. Suppose there are two types of individuals: those with $30,000.00 in the bank and those with $2,500.00 in the bank. Assume that individuals with $2,500.00 in the bank declare bankruptcy if they get in an accident. In bankruptcy, creditors receive only what individuals have in the bank. Assume that both types of individuals are only slightly risk averse. In this scenario, the actuarially fair price of full insurance, in which all damages are paid by the insurance company, is $ Assume that the price of insurance is set at the actuarially fair price. At this price, drivers with $30,000.00 in the bank likely v buy insurance, and those with $2,500.00 in the bank likely buy insurance. (Hint: For each type driver, compare the price of insurance to the expected cost without insurance.) Suppose a state law has been passed…
Use this information to answer Questions 2 trough 6: A high-school teacher in a low-income urban school in Worcester, Massachusetts, used cash incentives to encourage student learning in his AP statistics class. In 2010, 15 of the 61 students enrolled in his class scored a 5 on the AP statistics exam. Worldwide, the proportion of students who scored a 5 in 2010 was 0.15. Is this evidence that the proportion of students who would score a 5 on the AP statistics exam when taught by the teacher in Worcester using cash incentives is higher than the worldwide proportion of 0.15? Setup the appropriate null and alternative hypotesis.

A paper included analysis of data from a national sample of 1,000 Americans. One question on the survey is given below. "You owe $3,000 on your credit card. You pay a minimum payment of $30 each month. At an Annual Percentage Rate of 12% (or 1% per month), how many years would it take to eliminate your credit card debt if you made no additional charges?" Answer options for this question were: (a) less than 5 years; (b) between 5 and 10 years; (c) between 10 and 15 years; (d) never-you will continue to be in debt; (e) don't know; and (f) prefer not to answer. A USE SALT (a) Only 355 of the 1,000 respondents chose the correct answer of "never." Assume that the sample is representative of adult Americans. Is there convincing evidence that the proportion of adult Americans who can answer this question correctly is less than 0.40 (40%)? Use the five-step process for hypothesis testing (HMC3) described in this section and a = 0.05 to test the appropriate hypotheses. (Hint: See Example…
There is a 0.9991 probability that a randomly selected 33-year-old male lives through the year. A life insurance company charges $166 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit. Complete parts (a) through (c) below. a. From the perspective of the 33-year-old male, what are the monetary values corresponding to the two events of surviving the year and not surviving? The value corresponding to surviving the year is $ The value corresponding to not surviving the year is $ (Type integers or decimals. Do not round.) b. If the 33-year-old male purchases the policy, what is his expected value? The expected value is $ (Round to the nearest cent as needed.) c. Can the insurance company expect to make a profit from many such policies? Why? because the insurance company expects to make an average profit of $ on every 33-year-old male it insures for 1 year. (Round to the nearest cent as needed.)
