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

Question
Business Weekly conducted a survey of recent graduates from the top MBA programs. On the basis of the
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
OX ~ binomial and at least 5 successes and failures
OX
~ normal orn > 30
