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.
No the result will not be the original quantity, it will be less than the original.
Example: 100 increased by 25% becomes 125. 125 decreased by 25% becomes 93.75. This holds true for any number.
This is because you are taking 25% of the marked up number and not the original number.
