Answer:
"0.9739" is the correct answer.
Step-by-step explanation:
The given values are:
The ratio of true to false effects,
= 0.07
The power of study,
= 0.8
Alpha level,
= 0.05
Now,
The percentage of effects proved as significant will be:
= 
= 
0r,
=
%
The percentage of false effects will be:
= 
= 
or,
=
%
The total effects will be:
= 
=
%
hence,
The probability that this effect is real will be:
= 
= 
So this may not be 100% right they do it different in some schools but the way I do it is,
Two point Nineteen
In some cases it would be,
Two point Nineteenth
