Answer:
The margin of error is of 0.01.
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 = 1.037.
The margin of error is of:

In which
is the standard deviation of the population and n is the size of the sample.
Standard deviation was 0.21.
This means that 
Sample of 450:
This means that 
What is the margin of error, assuming a 70% confidence level, to the nearest hundredth?



The margin of error is of 0.01.
23 10/100 is how you would write it
Day = 24 hours, right?
36000/24 = 1500
If I put this into words:
36000 people per 24 hours = 1500 people per 1 hour
On average, 1500 people ride the bus per hour (or each hour)
Answer:
64/125 cubic meter
Step-by-step explanation:
volume = l × b × h
volume of a cube = s × s × s
∴ 4/5 × 4/5 × 4/5 = 64/125
