A random sample of n people selected from a large population will be asked whether they have read a novel in the past year. Let the random variable R represent the number of people from the sample who answer yes. The variance of random variable R is 6. Assume the responses are independent of each other. If the proportion of people from the population who read a novel in the past year is 0.40, which of the following is the best interpretation of random variable R ?
-
A binomial variable with 15 independent trials
-
A binomial variable with 25 independent trials
-
A variable that is not binomial with 25 independent trials
-
A binomial variable with 40 independent trials
-
A variable that is not binomial with 40 independent trials

One question on a survey asked whether people believe in hell. Of the possible responses, 484 answered "Yes, definitely," and 588 did not respond with "Yes, definitely." Find the point estimate of the population proportion who would have answered "Yes, definitely" when asked whether they believe in hell. What is the point estimate of the population proportion who would have answered "Yes, definitely"? (Round to three decimal places as needed.)

Suppose voters from a simple random sample of 500 (N
> 1,000,000) are interviewed and asked which presidential
candidate they're going to vote for. Of these, 35% say they'll vote
for the Statistics Party. You want to know the probability,
assuming this proportion is correct for the population, that more
than 40% of a random sample of 500 people will vote for the
