Question:-
If one state occurred four times in hundred observations while using the work-sampling technique, then the precision of the study using a 95% confidence level will be
Option (A)
90%
Option (B)
92%
Option(C)
95%
Option(D)
98%
Correct Option:
(D)
Question Solution:
P = (4/100) = 0.04
P.s = k.sp

S = (ksp/P)= (2 x 0.0196/0.04) = 0.979 @ 0.98
\ Confidence factor is 98%
