In a recent poll, 4545% of survey respondents said that, if they only had one child, they would prefer the child to be a boy. Suppose you conducted a survey of 160 randomly selected students on your campus and find that 79 of them would prefer a boy.(a) Use the normal approximation to the binomial to approximate the probability that, in a random sample of 160 students, at least 79 would prefer a boy, assuming the true percentage 45%. (b)...

Problem 6 Five applicants for a job are ranked according to ability, with being the best. These rankings are unknown to an employer, who simply hires two applicants at random. What is the probability that this employer hires exactly one of the two best applicants? Problem 7 Five motors ( through 5) are available for use, and motor 2 is defective. Motors 1 and 2 come from supplier I, and motors 3, 4, and 5 come from supplierIL. Suppose two...

A survey of drivers in the United States found that 15% never use a cell phone while driving. Suppose that drivers arrive at random at an auto inspection station. If the inspector checks 10 drivers, what is the probability that at least one driver never uses a cell phone while driving? (Round your answer to the hundredth.) Suppose the inspector checks 1000 drivers. Use the normal approximation to the binomial distribution to find the approximate probability that at least 13%...

A Gallup poll of 1,236 adults showed that 12% of the respondents believe that it is bad luck to walk under a ladder. Suppose 30 people are selected at random from among the 1,236 were polled, and further suppose we want to calculate the probability that at least 2 of the 30 believe it is bad luck to walk under a ladder. Given that the 30 subjects were selected without replacement, those selections are not independent. Can the probability be...

In a recent survey of 114 WMU graduates, 52 students said that parking was too limited on campus. What is the estimate of the population proportion? What is the standard error of this estimate? Question 1 options: 1) Estimate of proportion: 0.456, Standard error: 0.0044. 2) Estimate of proportion: 0.456, Standard error: 0.0466. 3) Estimate of proportion: 0.544, Standard error: 0.0466. 4) The true population proportion is needed to calculate this. 5) Estimate of proportion: 0.544, Standard error: 0.0044. Question...

1. Many companies use a incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...
