Answer:
Probability that effect is real = 0.97
Step-by-step explanation:
Given data :
ratio of true to false = 0.7
Alpha level = 0.05
power of study = 0.8
<u>Determine the probability that this effect is real </u>
From the question we can deduce : 70% of events are real , 30% of events are not real
% of real effect = 0.8 * 70% = 56%
% of false effect = alpha level * percentage of unreal events
= 0.05 * 30% = 1.5%
summation of effects = 56 + 1.5 = 57.5%
Hence probability that the effect is real
= 56% / 57.5%
= 0.9739 ≈ 0.97

Answer:
3x^2+5
Step-by-step explanation:
f(x) = 3x + 2 ; g(x) = x^2+ 1
(fºg)(x) = 3(x^2+ 1)+2
(fºg)(x) = 3x^2+3+2
(fºg)(x) = 3x^2+5
