Answer:
by u meant 32n^4, then the answer is 2n^4
Step-by-step explanation:
first find the gcf of the coefficient
32 and 34
their gcf is 2, because they're both even but have no other common factor, so it is 2
then for the variables
n^4 and n^5
their gcf is n^4. you can tell by dividing each term by n^4
n^4 / n^ 4 = 1
n^5 / n^4 = n
so then 2 * n^4 is 2n^4
Answer:
The 99% confidence interval for the proportion of all students at this school who have their names written on their graphing calculators is (0.4652, 0.8148).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
A random sample of 50 students is selected, and of the students questioned, 32 had their names written on their graphing calculators.
This means that 
99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence interval for the proportion of all students at this school who have their names written on their graphing calculators is (0.4652, 0.8148).
