Step-by-step explanation:
Answer: = ( 0.0384, 0.1216)
Therefore at 95% confidence interval the difference between teenage female and male depression rates is between ( 0.0384, 0.1216)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 0.08
Standard deviation r = 0.03
Number of samples n = 2
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
0.08+/-1.96(0.03/√2)
0.08+/-1.96(0.021213203435)
0.08+/-0.0416
= ( 0.0384, 0.1216)
Therefore at 95% confidence interval= ( 0.0384, 0.1216)
<ABD and <EBC are equal to each other. In order to solve for the x value, set the equations equal to each other;
4x = 2x + 40,
x = 20
Based off what angle you are trying to find, you would plug x = 20 into the equation.
Answer:
D
Step-by-step explanation:
<em>x</em> is greater than 12:
and <em>x</em> is less than or equal to 3 times the value of y:
We can divide everything by 3:
