Suppose that 80% of adults with allergies report symptomatic relief with a specific medication and the medication is given to 10 randomly selected adults with allergies.

a. What is the plausible distribution of the number of adults out of 10 reporting symptomatic relief after taking the medication, normal, Poisson, or binomial? Find the mean and variance of the distribution you choose.

b.What is the probability that eight or more adults reporting symptomatic relief after taking the medication?

c. What is the probability that the number of adults reporting symptomatic relief after taking the medication is between 3 and 5 inclusive?

d. What is the probability that the number of adults reporting symptomatic relief after taking the medication is two standard deviations or more away from the mean?

Binomial Distribution Exercises Please answer all three as they are related, thank you! 4.3.4) The same survey database cited in Exercise 4.3.1 (A-5) shows that 32 percent of U.S. adults indicated that they have been tested for HIV at some point in their life. Consider a simple random sample of 15 adults selected at that time. Find the probability that the number of adults who have been tested for HIV in the sample would be: a. Three b. Less than...
