Question

#42 what do we call a data set where every bar in its histogram has the same height? (a) skewed (b) symmetric (c) bell - shaped (d) uniform (e) none of these #43 the empirical rule makes two (2) assumptions about a given data set. what are these two assumptions? (a) the data set must have a symmetric & uniform distribution. (b) the data set must have a skewed & uniform distribution. (c) the data set must have a skewed & uniform distribution. (d) the data set must have a symmetric & bell - shaped distribution. (e) none of the above

Explanation:

For #42, a uniform distribution in a histogram has bars of equal height. For #43, the Empirical Rule applies to symmetric and bell - shaped (normal) distributions.

Answer:

#42: D. uniform
#43: D. The data set must have a symmetric & bell - shaped distribution.
