According to the theory on the <em>effect size</em> the following statements are correct:
<em>As the standard deviation increases, the power of the test increases</em>. An increment of the standard deviation means that a larger sample size is required for the test and a larger sample size implies that the power increases, which means that as the standard deviation increases the power also increases.
<em>As the sample size increases, the power of a test increases</em>. When the sample size increases the amount of information increases, this means that the probability of rejecting H0 given that H0 is false increases. In other words, the probability that the significance test performs according to reality is larger.
Answer:
Step-by-step explanation:
4x + 2y = 6
isolate the y term
2y = -4x + 6
divide by the coefficient of y
y = -2x + 3

Answer:
Step-by-step explanation:
So this is a quadratic sequence.
3, 12, 22, 33, 45, 58, 72
9 10 11 12 13 14
9, 10, 11, 12, 13, 14
1 1 1 1 1
This means the next one must be 15 so
3, 12, 22, 33, 45, 58, 72, x
9 10 11 12 13 14 15
x= 72+15
x= 87
