Question

In a large company, it is assumed that 25% of the employees hold degrees in business. A random sample of 100 employees is selected, and their degrees are recorded. a. The sample finds that 22 employees hold degrees in business. What is the population parameter? Give the measure, its value, and its point estimate. b. What probability distribution will be used to determine the probabilities of particular sample proportions? Why? c. What is the value of the mean of the distribution from part b? d. What is the standard deviation of the distribution from part b (standard error)? e. What is the probability that a sample of 100 employees contains at least 22 employees with business degrees? f. What is the probability that a sample of 100 employees contains less than 28 employees with business degrees? g. What is the probability that a sample of 100 employees contains between 18 and 28 employees with business degrees?
