A random sample of size n = 101 is taken from a population of size N = 2,719 with a population proportion of p = 0.67. [You may find it useful to reference the z table.]

a-1. Is it necessary to apply the finite population correction factor?

  • Yes

  • No

a-2. Calculate the expected value and the standard error of the sample proportion. (Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.)

b. What is the probability that the sample proportion is greater than 0.68? (Use rounded standard deviation. Round "z" value to 2 decimal places and final answer to 4 decimal places.)
