survey, assume that 75% of the recent graduates annual salary exceeds $80000. Suppose you take a simple random sample of 60 recent graduates. Note: round all z scores to 2 decimal places and all other numbers to 4 decimal places. Find the probability that more than 65% of the 60 recent graduates have an annual salary exceeding $80000. Beyond representative sampling, what assumptions are needed to satisfy the requirements for this problem? OX ~ normal and n > 30 OX ~ binomial and both np and nq at least 5 ~ binomial and at least 5 successes and failures ~ normal or n > 30
