Which statement must be true according to the histogram?

A) The data is skewed, showing that the majority of the monthly rainfall amounts was between 2.01 and 4 inches.

B) The data is skewed, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

C) The data is symmetrical, showing that the majority of the monthly rainfall amounts was between 2.01 and 4 inches.

D) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Answer 1

Answer: D) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Step-by-step explanation:

A distribution that is symmetrical happens when the values of corresponding variables befall at regular rates. Also, the mean, median and mode appear at an identical point. Furthermore, a symmetric distribution is a type of frequency in which grafic representation the left side of the mirrors the right side.

In this case, the distribution shows that most of the monthly rainfall amounts were either less than 2.01 or greater than 4 inches.

Answer 2
