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:
=
=
