6. Suppose that the probability of getting an A in a particular course is 0.08, and assume that the all student grades are independent. If you randomly sample 20 students taking the course; a) Find the expected number of students that will get an A, and the standard deviation of number of students that will get an A. (b) Find the probability that no student gets an A. c) Find the probability that at most 2 students get an A...

5. Suppose the number of days it takes you to get a flu shot after it is available follows this equation: Y, 30 - 2Xi where Yİ is the number of days until you get the flu shot, and Xi is the number of people you know whọ have the flu. Further, suppose on average you know 2.3 people who have the flu, with standard deviation 5. Suppose that the population has size m 10 (a) Find the average time...

Suppose that a company selling flu vaccines says that it’s
effective if fewer than 20% of all those who get a flu shot
actually become sick with the flu. Let p = fraction of people who
have been given the flu shot and become sick anyway. You want to
test the following:
If 75 of 300 people given the vaccine also get sick from the
flu, what would you conclude given α = 0.05?
a) We fail to reject Ho,...

3. If you get the H1N1 Flu vaccine, not only are your chances of getting sick reduced, but you being healthy also benefits the people you interact with on a daily basis. a. Draw a graph showing the market for H1N1 flu shots. Assume that the marginal cost of each H1N1 flu shot is equal to the marginal social cost and that the demand curve is downward sloping (use Fig. 1 to help you get started). b. Will the marginal...

The experimentation of a new drug in a lab has two outcomes. The probability of getting the first result is 0.20. The probability of getting second result is 0.80. Let x be the number of the experiment results. Construct a probability distribution for the random variable x. If the experiment is repeated twice find the probability of a. Both having First result b. One first result and another is the second result c. Both having the second result Note :...
