1.Which of the following is not a characteristic of a binomial random variable?

a. n identical trials

b. probability of failure is the same for each trial

c. non-correlated outcomes for each trial

d. non of the above

2. Which of the following are not binomial random variables(multiple answers)

a. one hundred randomly selected individuals are asked about their opinion on health insurance

b. one hundred people at a bar are asked about whether they are for or against restricting the sale of alcohol

c. one hundred randomly selected people are asked if they are in favor of a single payer health care system

d. one hundred randomly selected individuals are asked abut their marital status

3. Supposed that the probability of a randomly selected individual developing side effects from a new diet is 20%. If ten subjects are testing the diet, what is the probability that exactly 3 individuals develop side effects? (enter your answer as follows: 10.1%)

4. Suppose that the probability of a randomly selected individual developing side effects from a new diet is 20%. If ten subjects are testing the diet, what is the probability that at most 3 individuals develop side effects? (enter your answer as follows: 10.1%)

5. Suppose that the probability of a randomly selected individual developing side effects from a new diet is 20%. What is the expected number of subjects that would develop side effects if 500 individuals tested the diet?

6. Suppose that the probability of a randomly selected individual developing side effects from a new diet is 20%. Would it be unusual if only 35 out of 400 individuals trying the diet developed side effects?

a. yes, since the probability of 35 cases out of 400 is less than 1%

b. yes, since the 35 cases are more than two standard deviation from the mean

c. all of the above

d. none of the above

A binomial random variable with parameters n and p represents the number of successes in n independent trials. We can obtain a binomial random variable by generating n uniform random numbers 1 2 n U ,U ,...,U and letting X be the number of i U that are less than or equal to p. (a) Write a MATLAB function to implement this algorithm and name the function gsbinrnd. You may use the for loop to generate random numbers. (b) Use...

X1 is a binomial random variable with n = 100 and p = 0.8, while X2 is a binomial random variable with n = 100 and p = 0.2. The variables are independent. The profit measure is given by P = X1 / X2. Run N = 10 simulations of X1 and X2 to simulate the distribution of P, and then find both the variance and the semi-variance.
