In a local university, 10% of the students live in the dormitories. A random sample of 100 students is selected for a particular study. a) What is the probability that the sample proportion (the proportion living in the dormitories) is between 0.172 and 0.178? b) What is the probability that the sample proportion is less than 0.025?
