Dr. V.R. Bencivenga and Dr. Stephen Donald Economics 329 HOMEWORK QUESTION - Belief in global warming In a large city a certain (unknown) proportion of adults believe that global warming is a liberal hoax designed to hurt oil companies. You plan to take a survey of n adults to "estimate" this proportion. You want to be able to say that your estimate is within three percentage points (i.e., within 0.03) of the true proportion, with 0.95 probability. What is the smallest sample size that guarantees that you would obtain a satisfactory estimate (an estimate that's within 0.03 of the true proportion, with probability 0.95)? Provide an answer using an approximation based on the Central Limit Theorem a. 752 b. 2135 c. 4269 d. 1068

An elevator has a placard stating that the maximum capacity is 1610 lb---10 passengers. So, 10 adult male passengers can have a mean weight of up to1610 divided by 10 = 161 pounds. If the elevator is loaded with 10 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than161lb. (Assume that weights of males are normally distributed with a mean of 165 lb and a standard deviation of 35 lb.)Does this elevator appear to be safe?The probability the elevator is overloaded is?(Round to four decimal places as needed.)
