Q83 answer given in official answer key is option (2) but none of the option is correct.
Q96 The Standard Deviation (S.D.) and mean of two groups A and b are given below.
Group Standard Deviation Mean
A 3 70
B 4.2 60
The true statement among the following is
I. A is more consistent than B
II. B is more consistent than A
III. A is more efficient than B
IV. B is more efficient than A
1) Only I and III are true
2) Only I and IV are true
3) Only II and III are true
4) Only II and IV are true
Sol. Coefficient of Variation of group A = (3/70)*100 = 4.28
Coefficient of Variation of group B = (4.2/60)*100 = 7
Since coefficient of variation of A < coefficient of variation of B
Hence A is more consistent
Also mean of A > Mean of B
Hence A is more efficient
Thus, Statement I and III are true
(More objections will be soon uploaded with their correct explanation)
