- A researcher believes that about 70% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 170 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that fewer than 122 of the 170 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity.
