# Question: The paper The Effect of Temperature and Humidity on Size

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:

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.
