You are an educational researcher for McMaster University. You know that a particular program at the university has 1149 students, 45% of which are in first year. Using this information, if you were to take a sample of 87 students from the program, what would be the expected value (mean) and the standard deviation of the distribution for sample proportion? Round your sample standard deviation to four decimal places, and expected sample proportion to two decimal places.
