The square root of 4 is 2 which means that 2x2 is 4
4x + 2x + 2
= 6x + 2
So the answer is B
I believe it’s the second option because there are two 3’s with different outputs
Answer:
A sample of 17 must be selected.
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 Z-table as such z has a p-value of
.
That is z with a pvalue of
, so Z = 2.054.
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.
The standard deviation from a previous study is 4 hours.
This means that 
How large a sample must be selected if he wants to be 96% confident of finding whether the true mean differs from the sample mean by 2 hours?
A sample of n is required.
n is found for M = 2. So



Simplifying both sides by 2:



Rounding up:
A sample of 17 must be selected.
