A random sample of size n = 80 is taken from a population of size N = 600 with a population proportion p = 0.46.

Is it necessary to apply the finite population correction factor?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.)

What is the probability that the sample mean is less than 0.40? (Round \"expected value\" to 2 decimal places and \"Standard error\" to 4 decimal places. Round your final answer to 4 decimal places.)
