Answer:
4%
Step-by-step explanation:
Given data
The total sales= $8900
Donated amount=$356
Hence the percent donated is
=Donated amount/Total Sales *100
= 356/8900*100
=0.04*100
=4%
Hence the donated percent is 4%
Answer:
The margin of error for a confidence interval for the population mean with a 90% confidence level is 0.53 hours.
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 quesstion:
So
The margin of error for a confidence interval for the population mean with a 90% confidence level is 0.53 hours.
The domain is {8, 9, 10, 11, 12}.
The domain is the set of input values; in this function, the input values are u, the number of uniforms. If there are at least 8 but no more than 12 players, they will need between 8 and 12 uniforms. We will only use whole numbers for this, since we will not have pieces of uniforms. This means the whole numbers between 8 and 12 will make up the domain.
