Water Taxi Safety When a water taxi sank in Baltimore’s Inner Harbor, an investigation revealed that the safe passenger load for the water taxi was 3500 lb. It was also noted that the mean weight of a passenger was assumed to be 140 lb. Assume a “worst-case” scenario in which all of the passengers are adult men. Assume that weights of men are normally distributed with a mean of 188.6 lb and a standard deviation of 38.9 lb (based on Data Set 1 “Body Data” in Appendix B). a. If one man is randomly selected, find the probability that he weighs less than 174 lb (the new value suggested by the National Transportation and Safety Board). b. With a load limit of 3500 lb, how many male passengers are allowed if we assume a mean weight of 140 lb? c. With a load limit of 3500 lb, how many male passengers are allowed if we assume the updated mean weight of 188.6 lb? d. Why is it necessary to periodically review and revise the number of passengers that are allowed to board?

Roll a die and consider the following two events={2, 3, 6}, event ={1, 5, 6}. Are the events E and F independent?Choose the correct answer below.- No, because the probability of F occurring is higher if it is known that E has occurred.- No, because there is at least one roll which leads to both E and F occurring.- Yes, because the probability of F occurring is higher if it is known that E has occurred.- Yes, because each roll of the die is an independent event.
