A researcher believes that about 70% of the seeds planted with the aid of a new chemical fertilizer willgerminate. He chooses a random sample of 200 seeds and plants them with the aid of the fertilizer.Assuming his belief to be true, approximate the probability that at least 137 of the 200 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.)0X

Previously, De Anza's statistics students estimated that the amount of change daytime statistics students carry is exponentially distributed with a mean of $0.88. Suppose that we randomly pick 25 daytime statistics students. Find the probability that an individual had between $0.80 and $1.00. Graph the situation, and shade in the area to be determined.
A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period.
