1. If 40% of high school students said that they exercise regularly, find the probability that 5 randomly selected high school students will say that they exercise regularly. Would you consider this event likely or unlikely to occur? Explain your answer.

Solution

Population proportion for exercise = 40%

Sample size = 5

Here X no of students who say that they exercise regularly follow a Binomial with p = 0.4 and n =5

Required prob = P(x =5)

= (0.4)⁵
