The flu shot in a given year has an 84% chance of preventing the flu on those it is administered to. What is the probability that if 4 people get the flu shot, the flu shot prevents the flu for all 4 of them, assuming independence?
Homework Answers
X ~ Binomial (n,p)
P(X) = nCx px (1-p)n-x
So,
P( X = 4) = 4C4 0.844 0.160
= 0.4979

Let S be the event that a randomly chosen person has received a flu shot this year. Let F be the event that a randomly chosen person has had the flu this year. Place the correct event in each response box below to show: Given that the person has received a flu shot this year, the probability that a randomly chosen person has had the flu this year.

5. Suppose the number of days it takes you to get a flu shot after it is available follows this equation: Y, 30 - 2Xi where Yİ is the number of days until you get the flu shot, and Xi is the number of people you know whọ have the flu. Further, suppose on average you know 2.3 people who have the flu, with standard deviation 5. Suppose that the population has size m 10 (a) Find the average time...

Suppose that a company selling flu vaccines says that it’s
effective if fewer than 20% of all those who get a flu shot
actually become sick with the flu. Let p = fraction of people who
have been given the flu shot and become sick anyway. You want to
test the following:
If 75 of 300 people given the vaccine also get sick from the
flu, what would you conclude given α = 0.05?

Multiple Choice The government wants to know if billboards promoting the flu shot increases the number of people who get the flu shot. They placed 4 billboards in City A for 6 months and no billboards in City B. They then collected data from each city on the # of people who obtained a flu shot in the last 3 months. The statistics for both samples are as follows: Sample 1: City A Sample 2: City B # of flu...

A pediatrician has administered a flu vaccine to 1,000 children in a local community. The average number of children who contract the flu after they get vaccinated is 4 cases per 1,000 children. What is the probability that none of the 1,000 children will contract the flu this season? Hint: Use a Poisson distribution with λ = 4.

Suppose that a basketball player has a 28.31% chance of making any shot they take. If they were to take 34 shots in a given game, we would of course expect them to make 28.31% of them, but what would be the standard deviation in the number of shots made?

Between 4% and 21% of individuals in the US will catch the flu each year. Suppose you come up with a cure that " kind of" works. after countless testing for many years among millions of random patients, the data shows that if administered to randomly selected patient confirmed of having flu, the success rate for the cure is 15%. Assume biological factors among patients are random, and that no true correlation or causation has been discovered. Confirm whether or...
