Avoiding an accident when driving can depend on reaction time. That time, measured in seconds from the moment the driver sees danger until they step on the brake pedal, can be described by the Normal model ?(1.5,0.18).a) What percent of drivers have a reaction time of less than 1.25 seconds? b) What percent of drivers have a reaction time greater than 2 seconds?c) What percent of drivers have a reaction time between 1.35 and 1.75 seconds? d) Describe the reaction time of the slowest 10% of all drivers. e) Describe the reaction time of the fastest 5% of all drivers. f) In what interval of reaction times do the middle 60% of all drivers fall?
