questions below.
The sample proportion is 0.68. What is the population proportion?
(Type an integer or a decimal. Do not round.)
Because an approximate probability is desired, the Central Limit Theorem might be applicable. In order to use the Central Limit Theorem for a proportion, check the assumptions. The sample is random, and it is reasonable to assume the population size is at least 10 times
the sample size, which would be at least 2000. If a simple random sample of 200 independent people take the bar exam, how many of them would be expected to pass, on average? Calculate n times p. Also calculate how many would be expected to fail, n times (1- p).
State whether these are both more than 10.
