Answer:
And rounded up we have that n=656
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 80% of confidence, our significance level would be given by 
and 
. And the critical value would be given by:
Solution to the problem
The margin of error for the proportion interval is given by this formula:
(a)
Since we don't have prior info for the proportion of interest we can use 
as estimator. And on this case we have that 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=656
Answer:
9?
Step-by-step explanation:
its c a l c u l a t o r timeee.
-3 * 7= 21
21 - 12= 9
so now how do you put 9 in the thousands place it's just in the ones place which won't make sense
No it is not. There are 8 known planets in our solar system and all of them orbit the sun. There are also many dwarf planets.
Answer:
measure aggregate output by adding up the total expenditures by households. Then, if we assume that one person's spending is another person's income, an equivalent measure of the value of total output would be the total income reported by individuals.
