An insurance company reported that 55% of the high-speed chases result in a minor or major accident During in a month in which 40 high-speed chases occur, compute the following: Use Appendix B1. Areas under the Normal Curve to determine the z-valuets). (Round z-velues to 2 decimal places and when negative, indicate with a negative sign. Round probebilities to 4 decimal places) a. The mean and standard deviation. (Round them to 2 decimal places.) Mean Standard deviation b. The probability that the number of the accudents is 25 or greater Probability c. The probability that the number of the accudents is 15 or less. Probability d. The probability that the number of the accudents is between 15 and 25 inclusive. Use the normal approximation to the binamial distribution.
