A random sample of 60 professional economists was asked to predict whether next year’s inflation rate would be higher, lower than or about the same as in the current year. The results are shown in the following table. Test the null hypothesis that the professionals are evenly divided on the question.

Consider two people age 40. What is the expected number of years that both are alive? What is the expected number of years that at least one is alive? Show your work in excel to solve the following: What is the actuarial present value of a pension that pays $50,000 per year as long as at least one of the two 40-year-old people survive? Use a 5% discount rate. [Remember actuarial present value means that you must discount in the usual way to get present value, but you also must weight (i.e., multiply) every yearly payment by the probability that at least one of the two 40-year-old people is alive in order to receive the $50,000 payment.]

There is a 0.9988 probability that a randomly selected 32-year-old male lives throughout the year. A life insurance company charges $161 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $90,000 as a death benefit. Complete parts (a) through (c) below. a. From the perspective of the 32-year-oldmale, 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 $negative −161. The value corresponding to not surviving the year is $89839 (Type integers or decimals. Do not round.) b. If the32 -year-old male purchases the policy, what is his expected value? The expected value is $nothing. (Round to the nearest cent as needed.)
