A film distribution manager calculates that 9% of the films released are flops.
If the manager is right, what is the probability that the proportion of flops in a sample of 506 released films would differ from the population proportion by greater than 3%? Round your answer to four decimal places.
Suppose a steroid test is 81% sensitive and 85% specific. That is, the test
will produce 81% true positive results for steroid users and 85% true
negative results for non-steroid users. Suppose that 2.8% of people are
steroid users. If a randomly selected individual tests negative, what is the
probability he or she is a steroid user?
YOUR ANSWER SHOULD BE BETWEEN O AND 100 AND ROUNDED TO 4
DECIMAL PLACES.

- Compute the Posterior Probabilities by completing the tablearrow_forwardJUST ANSWER SUBPART 1 There are two individuals, Individual A and Individual B. Individual A has an income (Y) of 500 million Rupiah per year. If Individual A is sick, he will lose 25% of his income. Meanwhile, Individual B has an income (Y) of 100 million Rupiah per year, and if Individual B is sick, he will lose 75% of his income. The probability of Individual A and Individual B being sick is the same, which is 10%. If the satisfaction level of Individual A and Individual B is determined by their income level, based on the following function U(Y)=ln Y, would Individual A and Individual B prefer not to have health insurance?

- The probability that it will rain on any given day is 0.20, and the probability is independent from day to day. You are trying to decide whether or not to make a tee time tomorrow to play golf. This requires a commitment on your part of turning down, say, movie tickets in favor of playing golf. If you accept the tickets, you also make the commitment not to go golfing. There is a weather forecast that signals whether it will rain tomorrow or not. There is a 0.80 probability that it rains when there is a "rainy" forecast and a 0.125 probability of rain when there is a "sunny" forecast. The overall probability of getting a "rainy" forecast is 0.111. Assume you are risk neutral. You place the following monetary values on the potential outcomes: a sunny day at the golf course a rainy day at the movies a rainy day at home $95 $20 -$18 a sunny day at $1 the movies a.
