There are 30% registered voters who support candidate 1. A pollster will obtain a random sample of 2200 registered voters. Find the probability that at most 1500 of the individuals in the sample support 1?
Homework Answers
n = 2200, p = 0.3
mean = 2200*0.3 = 660
sd = sqrt(n*p*q) = 21.49 (approx)
P(at most 1500) = 
[Due to continuoity correction]
So, the probability is 1 in this case.
I hope this will help. Thank you.
