Extracted text: Example 3: Suppose 40% of all college students prefer an asynchronous online structure as opposed to a synchronous online class. A professor at a local community college went out and surveyed 100 students and asked them which type of format they preferred for their online classes: synchronous or asynchronous. Use this information to answer the following questions. It can be very useful to draw a quick sketch of what the problem is asking for. ATT 43 students preferring 100 a) Find the z-score that would correspond to a sample proportion of an asynchronous online structure. b) What is the probability that at least 45% of those students that were surveyed would prefer an asynchronous online format? c) What is the probability that less than 20% of those students that were surveyed would prefer an asynchronous online format?
