A study carried out to investigate the distribution of total braking time (reaction time plus accelerator-to-break movement time, in ms) during real driving conditions at 60 km/hr gave the following summary information on the distribution of times ("A Field Study on Braking Responses Dring Driving," Ergonomics, 1995: 1903-1910): mean = 535 , s = 80 . Assume the braking times have approximately a bell shaped distribution. A) Approximately what percentage of braking times are in the interval (535, 615)?B) What value do the top 2.5% of braking times exceed? (show work)
