What is the probability that 25% or fewer male employees will indicate that they have to pick up the slack for moms working flextime? b. What is the probability that 20% or fewer male employees will indicate that they have to pick up the slack for moms working flextime? c. If a random sample of 500 is taken, how does this change your answers to (a) and (b)?
