Question

O

Answer 1

The true statements are:

A. Tree A's heights are less spread out than tree B's heights and

B. Tree A has lower average height than tree B

Explanation:

Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.

The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.
