*** *** *** National *** *** *** of Namibia, the probability *** *** trac fatality *** *** intoxicated *** *** *** is *** If eight trac *** observed last month.
a. *** the probability *** *** *** of *** *** or *** driver is *** *** the *** value *** standard *** *** *** *** *** intoxicated or *** drivers.
Solution
Let *** the number *** an *** *** *** driver.
Letp= 0:4be *** *** that a *** fatality *** involve *** intoxicated *** alcohol-impaired driver.
Then the *** *** Xfollows Binomial distribution, *** *** *** *** *** *** *** function of *** (X *** = *** *** :4) *** *** 8
*** x = *** *** *** :
a. The *** exactly 10 of the students will correctly identify Coke *** *** *** = 3) *** *** *** :4) 3
(1 *** 8
*** *** *** *** *** *** standard deviation of *** number *** intoxicated *** *** drivers is
E *** *** *** *** 8 0:4
= *** *** *** deviation of the number of intoxicated *** alcohol-impaired *** *** *** *** *** np
