Question

13. If the observations are 5
and -5, their geometric mean is
A. 5
B. -5
C. 0
D. none of the above​

Answer 1

Answer:D none of the above

Step-by-step explanation: because we can calculate geometric mean of positive numbers only..

Answer 2

Answer:

D) none of the above

Step-by-step explanation:

In mathematics, the geometric mean is a mean or average, which indicates the central tendency or typical value of a set of numbers by using the product of their values

now as per this ,

geometric mean will be

√5×(-5)= √-25= -5

as the answer is in negative.

we know ,

The geometric mean of numbers cannot be negative. If any of the terms in the sequence are, then we might get the imaginary numbers as the geometric mean. However, the basic fact is that the geometric mean applies to only non-negative integers, i.e. positive numbers (means natural numbers)
