Objective: Probability involving percentages Business Weekly conducted a survey of recent graduates from the top MBA programs. On the basis of the survey, assume that 80% of the recent graduates annual salary exceeds $55000. Suppose you take a simple random sample of 77 recent graduates. Note: round all z scores to 2 decimal places and all other numbers to 4 decimal places. 1. Find the probability that less than 90% of the 77 recent graduates have an annual salary exceeding $55000. 2. Beyond representative sampling, what assumptions are needed to satisfy the requirements for this problem? a) X~normal or n≥30 b) X~binomial and at least 5 successes and failures c) X~binomial and both npnp and nqnq at least 5 d) X~normal and n≥30
