Question

determine whether the statement is true or false. if it is false, rewrite it as a true statement. a graph of the cumulative frequencies can decrease from left to right. choose the correct answer below. a. the statement is false. the graph of cumulative frequencies always starts at the upper boundary of the first class and increases to the lower boundary of the last class, and therefore always increases from left to right. b. the statement is false. the graph of cumulative frequencies always starts at the upper boundary of the last class and decreases to the lower boundary of the first class, and therefore always decreases from left to right. c. the statement is true. the graph of cumulative frequencies can start either at the lower boundary of the first class or the upper boundary of the last class. d. the statement is false. the graph of cumulative frequencies always starts at the lower boundary of the first class and increases to the upper boundary of the last class, and therefore always increases from left to right.

Explanation:

A cumulative - frequency graph starts at the lower boundary of the first class and increases as we move from left - to - right until we reach the upper boundary of the last class. So, the statement that the graph of cumulative frequencies can decrease from left to right is false.

Answer:

A. The statement is false. The graph of cumulative frequencies always starts at the lower boundary of the first class and increases to the upper boundary of the last class.
