Suppose you want to create a mental picture of the relative frequency histogram for a large data set consisting of 1000 observations, and you know that the mean and variance of the data set are 36 and 9, respectively.
a. If you are fairly certain that the relative frequency distribution of the data is moundshaped describe the distribution of the data.
b. If you have no prior information concerning the shape of the relative frequency distribution describe the distribution of the data.
