The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 8 minutes. Find the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes. Question 1 Find the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes. (Simplify your answer. Round to three decimal places as needed.) Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 153 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 39 voted ... The probability that fewer than 39 of 153 eligible voters voted is (Round to four decimal places as needed.) Question 14 Engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all adults. (Accommodating 100% of adults would require very wide seats that would be much too expensive.) Assume adults have hip widths that are normally distributed with a mean of 14.3 in. and a standard deviation of 1.1 in. Find P99. That is, find the hip width for adults that separates the smallest 99% from the largest 1%. What is the maximum hip width that is required to satisfy the requirement of fitting 99% of adults? in. (Round to one decimal place as needed.) Question 7 Find the indicated z score. The graph depicts the standard normal distribution with mean 0 and standard deviation 1. The indicated z score is (Round to two decimal places as needed.) Question 2 0.2981 z O In a survey of 1424 people, 1057 people said they voted in a recent presidential election. Voting records show that 72% of eligible voters actually did vote. Given that 72% of eligible voters actually did vote, (a) find the probability that among 1424 randomly selected voters, at least 1057 actually did vote. (b) What do the results from part (a) suggest? (a) P(X 1057) = (Round to four decimal places as needed.) Question 15
