Answer:
The administrator should sample 968 students.
Step-by-step explanation:
We have 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 p-value of , so Z = 1.555.
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.
Standard deviation of 300.
This means that
If the administrator would like to limit the margin of error of the 88% confidence interval to 15 points, how many students should the administrator sample?
This is n for which M = 15. So
Dividing both sides by 15
Rounding up:
The administrator should sample 968 students.
Answer:
Four
Step-by-step explanation:
The degree of a polynomial is the highest of the degree of the monomials with non-zero co-efficient. In this problem we are given the polynomial:
The degree of the polynomial is 4.
For a polynomial of <em>n- degree </em>we have <em>n solutions counting multiplicity</em>.
So for this four degree polynomial we would have 4 solutions. Could be real or complex depending on the equation.
