Answer:
We need a sample size of at least 650
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.
In this problem:
We need a sample of size at least n
n is found when 
So
Rounding up
We need a sample size of at least 650
Answer:
6.32
Step-by-step explanation:
Also known as 2√10
After we solve that we get 6.32455532
we then focus on these numbers here
6.3<em>24</em>55532
It doesnt round up stays the same so we get 6.32 to nearest hundredth
Answer:
that is already in scientific notation
Step-by-step explanation:
if you are asking for what's the actual number, then it's 0.000678
