7. [-/3 Points] DETAILS PODSTAT6 8.R.036.S. MY NOT Suppose that 39% of all U.S. employees contribute to a retirement plan (p = 0.39). LL USE SALT (a) In a random sample of 100 employees, what is the approximate probability that at least half of those in the sample contribute to a retirement plan? (Round your answer to four decimal places.) (b) Suppose you were told that at least 68 of the 100 employees in a sample from your state contribute to a retirement plan. Would you think p = 0.39 for your state? Explain. (Round your answer to four decimal places,) If p = 0.39, the probability that at least 68 of the 100 employees in a sample from the state contribute to a retirement plan is . Thus, it seems unlikely v that p = 0.39 for the state. Viewing Saved Work Revert to Last Response
