Question

1. According to the CDC, approximately 46% of the population received a flu shot last year. If you randomly selected 3 people, fill in the following probability distribution for the X = the number of people who received the flu vaccine. Round your answers to FOUR decimal places.

2. Suppose you're doing a binomial question with n = 6 and p = 0.8. Which of the following will give the correct value for the probability that the number of successes is more than or equal to 5?

binomcdf(6, 0.8, 4)

1 - binomcdf(6, 0.8, 5)

binompdf(6, 0.8, 5)

binompdf(6, 0.8, 5) + binompdf(6, 0.8, 6)

1- binomcdf(6, 0.8, 6)

1 - binomcdf(6, 0.8, 4)

binomcdf(6, 0.8, 5)

binomcdf(6, 0.8, 6)

X 0 1 2 3 P(X)

Explanation / Answer

1 The probability distribution table will be:

2. 1 - binomcdf(6, 0.8, 4); Option F is correct.

x 0 1 2 3 p(x) 0.1575 0.4024 0.3428 0.0973
