What is the difference between discrete and continuous probability distributions? We will solve this problem with Excel Using BINOMDIST. Suppose that 48% of individuals 85 years and older have Alzheimer’s Disease. You go to a nursing home that has been feeding residents a diet consisting of natural, organic, and healthy foods including free range chickens, omega 3 eggs, flax seed, etc. You find that only 29 of 100 residents who are 85-years and older have Alzheimer’s disease? What is the likelihood of this outcome? Use the formula for the corresponding probability distribution to solve the problem.

1.Which probability distribution would you use to calculate the probability of success or failure of Advanced Researcher's vaccine if it were to be administered to people in society?
A television program reported that the U.S. (annual) birth rate is about 16 per 1000 people, and the death rate is about 7 per 1000 people. (a) Explain why the Poisson probability distribution would be a good choice for the random variable r = number of births (or deaths) for a community of a given population size? Frequency of births (or deaths) is a common occurrence. It is reasonable to assume the events are independent.Frequency of births (or deaths) is a rare occurrence. It is reasonable to assume the events are independent. Frequency of births (or deaths) is a common occurrence. It is reasonable to assume the events are dependent.Frequency of births (or deaths) is a rare occurrence. It is reasonable to assume the events are dependent. (b) In a community of 1000 people, what is the (annual) probability of 6 births? What is the probability of 6 deaths? What is the probability of 17 births? 17 deaths? (Round your answers to four decimal places.) P(6 births) = P(6 deaths) =…

Do you think new package labeling or doing nothing is best? You will want to calculate the percent of bars produced that are within 5 grams of 1000 grams and the percent of bars produced that are within 5 grams of 990 grams. In other words, given a uniform distribution between 980 and 1000, what is the probability of being between 995 and 1005 and what is the probability of being between 985 and 995?
