A person must score in the upper 2% of the population on an IQ test to qualify for membership in Mensa, the international high-IQ society. If IQ scores are normally distributed with a mean of 100 and a standard deviation of 10, what score must a person have to qualify for Mensa? Every day Cara runs for five miles. Suppose that the time it takes her to complete the run is a random variable that is normally distributed with a...

If a person takes the bus 30 times a month commuting between his dorm and the Dining Hall. It takes the bus 10 minutes to run one loop. The waiting time, in minutes, for a bus to arrive is uniformly distributed on the interval [0, 10]. Suppose that waiting times on different occasions are independent. What is the standard deviation of the mean waiting time in minutes of a month? Round your answer to three decimal digits. What is the...
