Problem Four : Over the course of a clinical trial, 8,000 participants are given a trial drug for migraines. Suppose that the probability of the drug reducing migraines is 0.65. 1. What is the probability that precisely 5250 participants will experience a reduction in migraines? 2. What is the probability that at least 5250 participants will experience a reduction in migraines? 3. What is the expected number of participants who will experience a reduction in migraines? 4. What is the variance of the number of people who will experience migraines? 5. What is the probability that no more than 3000 participants will not experience a reduction in migraines?

9. The probability of flu symptoms for a person not receiving any treatment is 0.036. In a clinical trial of a common drug used to lower​ cholesterol, 42 of 1089 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu​symptoms, estimate the probability that at least 42 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the​ drug? A. P(X≥4242​) = (Round to four decimal places...

In the problem, make sure that you are clearly defining random variables, stating their distributions, and writing down the formulas that you are using. (That is, write down the pmf, write down mean and variance formulas.) The number of particles emitted by a radioactive source over the course of an hour is generally well modeled by a Poisson distribution. (We will see some solid justification of this later on when we discuss the gamma and exponential distributions.) Suppose that the...

Problem 1: Relations among Useful Discrete Probability Distributions. A Bernoulli experiment consists of only one trial with two outcomes (success/failure) with probability of success p. The Bernoulli distribution is P (X = k) = pkq1-k, k=0,1 The sum of n independent Bernoulli trials forms a binomial experiment with parameters n and p. The binomial probability distribution provides a simple, easy-to-compute approximation with reasonable accuracy to hypergeometric distribution with parameters N, M and n when n/N is less than or equal...

A medical researcher would like to determine how effective a new form of knee surgery is for treating knee pains. (In particular, is there a relationship between surgery status and pain reduction status?) He gathers 500 people with knee pain who are scheduled to have this surgery, and 500 people with knee pain who are not scheduled to have this surgery. He follows up with both groups after 2 months and determines the number of participants of each group who...

Pfizer was established in 1849 in Brooklyn, New York by cousins Charles Pfizer and Charles Erhart with a loan of $2,500 from Pfizer’s father.2 Today, 167 years later, Pfizer Inc. has international revenues of $49 billion, which makes it the second-largest pharmaceutical manufacturer in the world.3 Despite Pfizer’s success, the company has faced many challenges over the last few decades. The pharmaceutical industry is heavily influenced by legal, political, and technological forces, and all indications are that the industry will...
