D) 239
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
Required sample size:
Is n
n is found when
We have that
So
Simplifying by 6
We round up, and the answer is 239.
Answer:
y=2/3x
Step-by-step explanation:
First, we have to find the slope, which is
(-3-1)/(-2-4)
-4/-6
2/3 is slope.
y=2/3x+-___
substitute in -3 from first point
y=-2+__=-2
y=2/3x+0
y=2/3x
