A rainstorm in Portland, Oregon, wiped out the electricity in 10% of the households in the city. Suppose that a random sample of 60 Portland households istaken after the rainstorm.Answer the following.(If necessary, consult a list of formulas.)(a) Estimate the number of households in the sample that lost electricity by giving the mean of the relevant distribution(that is, the expectation of the relevant random variable). Do not round your response.?(b) Quantify the uncertainty of your estimate by giving the standard deviation of the distribution. Round your responseto at least three decimal places.

Let p be the proportion of households that lost electricity. Given that p = 10% = 0.10 Let X denotes…

34% of CSU students participate in the Statistics Games while they attend CSU. You take a random sample of 40 students. You want to determine the probability that more than 15 of them have participated in the Statistics games. Since the conditions are met, you decide to use the Normal model to find your answer. What is the mean and standard deviation of the sampling distribution?
