CR7.8 The paper “The Effect of Temperature and Humidity on Size of Segregated Traffic Exhaust Particle Emissions”

(Atmospheric Environment [2008]: 2369–2382) gave the following summary quantities for a measure of traffic flow

(vehicles/second) during peak traffic hours at a particular location recorded daily over a long sequence of days:

Mean 5 0.41 Standard Deviation 5 0.26 Median 5 0.45 5th percentile 5 0.03 Lower quartile 5 0.18 Upper quartile 5 0.57 95th percentile 2 0.86 Based on these summary quantities, do you think that the distribution of the measure of traffic flow could have been approximately normal? Explain your reasoning.
