Question

Q1:

If

i

x

and

i

y

(

i = 1,2,......n

) are the positive values of two variables

X

and

Y

with geometric

mean

G1

and

G2

respectively, then determine the geometric mean of

Y

X

(ratio of

X

and

Y

) .



Q2:

Consider

n

values of a variable

X

is given as

i

x

(

i = 1,2,......n

). Out of these only one

value is found as zero

(0)

. If all the remaining values of

X

are found as real number, then

which of the following statements is correct ?

a) Arithmetic mean can be used as measure of central tendency.



b) Harmonic mean can be used as measure of central tendency.



c) Both arithmetic and Harmonic mean can be used as measure of central tendency.

d) Neither arithmetic nor Harmonic mean can be used as measure of central tendency.​
