This past February1 a survey of n-Canadians between the ages of 18 and 34 years of age. The finding? Sixty-three percent (63%) of Canadians between the ages of 18 to 34 admit they have been knowingly been the victim of fraud or scam(s) at some point in their lifetime. Let p represent the proportion of all Canadians between the age of 18 and 34 years of age who admit to have knowingly been a victim of fraud or scam(s) at some point in their life. From this poll, we can ascertain that p = 0.63. A pollster is to randomly pick n = 500 Canadians between the age of 18 and 34 years of age. Compute the probability/chance that between 60% to 70% of those chosen will admit to have knowingly been a victim of fraud or scam(s) at some point in their life.

A pollster is to randomly pick n = 500 Canadians between the age of 18 and 34 years of age.
Compute the
The proportion of all Canadians between the age of 18 and 34 years of age who admit to having knowingly been a victim of fraud or scam(s) at some point in their life is p =0.63
Sample size (n) = 500
Want to compute the probability/chance that between 60% to 70% of those chosen will admit to having knowingly been a victim of fraud or scam(s) at some point in their life.
Here p and n are given.
So normal approximation can be used to compute probability.
