How many in a car? A study of rush-hour traffic in San Francisco counts the number of people in each car entering a freeway at a suburban interchange. Suppose that the number of people per car in the population of all cars that enter at this interchange during rush hours has a mean of u 1.5 and a standard deviation of a 0.75. Could the distribution of the number of people per car be normal for the population of all cars entering the interchange during rush hours? Explain. Describe the shape of the sampling distribution of * for SRSS of size n 100 from the population of all cars that enter this interchange during rush nours. Justify your answer.

Tips given to taxi drivers form a substantial part of their income. They also serve as a loose metric of service quality that can be useful for taxi companies. An analysis of a large dataset shows that the tips given (as a percentage of taxi fares) are normally distributed with mean 21.3% and standard deviation 7.5%. Furthermore, tips received for different trips are independent from each other. taxi driver expects to do 2000 trips next year. For approximately how many of these trips will he receive a tip over 25%?
