Question

A company surveyed 2,600 North American airline passengers and reported that approximately 65% said that they carry a smartphone when they travel. Suppose that the actual percentage is 65%. Consider randomly selecting six passengers and define the random variable x to be the number of the six selected passengers who travel with a smartphone. The probability distribution of x is the binomial distribution with

n = 6

and

p = 0.65.

(Round your answers to four decimal places.)

Calculate

p(4).

multiple choice: Interpret this probability.

1. the probability that a random sample of 6 passengers will contain at least 4 passengers who travel with a smartphone

3. the probability that a random sample of 6 passengers will contain less than 4 passengers who travel with a smartphone

4. the probability that a random sample of 6 passengers will contain at most 4 passengers who travel with a smartphone

5. the probability that a random sample of 6 passengers will contain exactly 4 passengers who travel with a smartphone
