The given polynomial is:
The first step to factor taking out the GCF is to write each term in prime factored form, so:
The second step is to identify the factors common in all terms, they are: 3xcxd
Finally, factor out the GCF:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
Solution to the problem
For this case we can find the sample proportion for each observation with the following formula:
Where X represent the number of returns and n =100 for each case since the standard value used. Using the last formula we got:
And now witht those values we can find the sample mean of proportions with the following formula:
And we can find the standard error with the following formula:
So then the best option on this case is given by:
E) .0863
