=+68. A study carried out to investigate the distribution of total braking time (reaction time plus acceleratorto-brake 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 during Driving,” Ergonomics, 1995: 1903–1910):

mean 5 535 median 5 500 mode 5 500 sd 5 96 minimum 5 220 maximum 5 925 5th percentile 5 400 10th percentile 5 430 90th percentile 5 640 95th percentile 5 720 What can you conclude about the shape of a histogram of this data? Explain your reasoning.
