Power companies severely trim trees growing near their lines to avoid power failures due to falling limbs in storms. Applying a chemical to slow the growth of the trees is cheaper than trimming, but the chemical kills some of the trees. Suppose that one such chemical would kill 20% of sycamore trees. The power company tests the chemical on 250 sycamores. Consider these an SRS from the population of all sycamore trees. What is the probability that 24% or more of the trees in the sample are killed? Step #2: Calculate the mean and standard deviation of the sampling distribution. Use appropriate notation. Mean of the Sampling Distribution: Symbol = Formula = Answer: Standard Deviation of the Sampling Distribution: Symbol = Formula = Answer:
