Answer 1

Answer #1

since thus is the case of binomial distribution where p is the probablity that traffic fatality involves an intoxicated or alcohol-impaired driver or nonoccupant. and n=8

we knkw that the mean of binomial distribution is np so

Mean= 8×0.45 = 3.6

Interpretation :- On an average of 3.6 out of 8 traffic fatalities will involve an intoxicated or alcohol-impaired driver or nonoccupant.
