Vehicle speed on a particular bridge in China can be modeled as a normal distribution. If 5% of all vehicles travel less than 39.15 miles/hr and 10% travell more than 73.94 miles/hr, what are the mean and standard deviation of vehicle speed? [Note: For this question, find exact z-score values using Excel; for example, the NORMSINVO function] Mean: Standard deviation: (Round your answers to 3 decimal places, if needed.)
