A researcher believes that about 72% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 95 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that fewer than 70 of the 95 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.

A researcher believes that about 73% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 95 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that at most 72 of the 95 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)

A researcher believes that about 71% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 120 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that fewer than 87 of the 120 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.
