Suppose a novel respiratory disease has a 2% mortality rate. If 1,000 people catch the disease, how many would you expect to die from it? Give the distribution of the r.v. you’re using to model this situation, including parameter values. How many people would have to catch the disease for the number of expected deaths to rise to 100,000? To rise to 1,000,000?

The mortality rate from disease X in city A is 75/100,000 in persons 65 to 69 years old. The mortality rate from the same disease in city B is 150/100,000in persons 65-69 years old. The inference that disease X is two times more prevalent in persons 65 to 69 years old in city B than it is in persons 65-69 years old in city A is: Correct Incorrect, because of failure to distinguish between prevalence and mortality Incorrect, because of...

The mortality rate from disease X in city A is 60/100,000 in persons 50+ years old....

The mortality rate from disease X in city A is 60/100,000 in persons 50+ years old. The mortality rate from the same disease in city B is 120/100,000 in persons 50+ years old. 1. Is the inference correct that disease X is two times more prevalent in persons 50+ years old in city B than it is in persons 50+ years old in city A? Why or why not? In 2000, there were 65,000 deaths due to lung disease in cigarette...

3) Say an individual has a respiratory disease that causes less CO2 to be exhaled with each breath. a) Would this tend to cause acidosis or alkalosis of the extracellular fluid? Why? b) Over the long term, how would the body compensate to bring pH back to normal, even though problems with CO2 exhalation remain?

Consider a country which currently has a constant total fertility rate, a constant mortality rate, and no emigration or immigration. Explain why the population growth rate could still be changing over time.

Suppose that 1000 people are randomly selected and tested for a particular disease that is present in 1.2% of the population. Assume that the test will perfectly identify the disease presence/abscence in each tested individual. For the following, for each numerical response, round your answer to at least 4 decimals(when necessary). -Use a binomial distribution to find the probability that at least 20 people test positive for the disease. -Approximate the previous probabilty by using the normal distribution. -Use a...

Suppose that, in an urban population, 50% of people have no exposure to a certain disease,...

Suppose that, in an urban population, 50% of people have no exposure to a certain disease, 40% are asymptomatic carriers, and 10% have the disease with symptoms. In a sample of 20 people, we are interested in the probability that the sample contains a number of asymptomatic carriers that is exactly thrice the number that have the disease with symptoms. While the final numerical answer is important, the setup of the solution is moreso.

2. Suppose that BioNTech discovers a vaccine that cures a disease. BioNTech has laboratories in both the United States and Germany and can manufacture the vaccine on both countries with the following total cost function: ?(?) = 10? where ? = ?1 + ?2. In Germany and the United States, the demand functions for the vaccine are ?1 = 70 − ?1 (Germany) ?2 = 110 − ?2 (The United States) a) If the firm can practice third-degree price discrimination,...
