100
If 70% of people do not believe in ghosts, design a simulation using the numbers 1-100 to represent the probability of selecting a non-believer in a class of 20
Generate 20 numbers using the numbers 1-100. 1-70 represent a non-believer and 71-100 represent a believer. Count how many #s between 1-70 you get and divide by 20 to find the probability

According to the US census bureau, 21% of 16 year olds get into car accidents. If SHS has an average of 15% with a margin of error 5% can you claim that SHS are safer drivers
Yes because 21% is outside the average and margin of error 15% with MoE of 5% gives a range from 10-20% of 16 year olds in an accident
