Below is a distribution of race in the United States from 2014.
White= 60.5%
Black= 12.5%
Hispanic= 18.3%
Asian= 5.7%
Other= 3%
If we were to randomly choose 150 people for a survey, what is the probability that less than 70 of them would be white (round to 3 decimal places)?
Would this be unusual? If so, give some reasons why a particular sample might have less than 70 whites.
What is the probability that we would randomly choose a sample of 150 people and more than 22 of them were black (to 3 decimal places)?
What is the probability you would randomly select two Americans and they would both be white?
How many Asian people should we expect to have in a randomly selected group of 150 people?
