The following histogram is obtained from the daily rainfall amounts (in.) in Boston for a year. If we want to conduct a hypothesis test of a claim about the mean, there is a requirement that the population of rainfall amounts must have a normal distribution.

Based on the histogram, does it appear that the population satisfies the requirement of a normal distribution? Why or why not?
