QUESTION:

Problem 30CQ

UnemploymentIf 8% of all people in a certain geographic region are unemployed, find the probability that in a sample of 200 people, there are fewer than 10 people who are unemployed.

ANSWER:

Solution :

Step 1 of 1:

Let n denotes the total people is 200.

Let p denotes 8% (0.08) of all people are unemployed.

We need to find q value.

q = 1-p

q = 1-0.08

q = 0.92

Hence, q=0.92.
