Problem 4BSC

Normal Distribution When it refers to a normal distribution, does the term “normal” have the same meaning as in ordinary language? What criterion can be used to determine whether the data depicted in a histogram have a distribution that is approximately a normal distribution? Is this criterion totally objective, or does it involve subjective judgment?
