Answer:
Given:You sample 160 men, and 25% own cats
You sample 120 women, and 20% own cats.
To Find : Find the test statistic, rounded to two decimal places.
Solution:
You sample 160 men, and 25% own cats.
No. of men have cats =
=
So,
You sample 120 women, and 20% own cats.
No. of women have cats =
=
So,
We will use Comparing Two Proportions
Let and be the probabilities of men having cat and women having cat receptively
Formula of test statistic :
Substitute the values
test statistic :
test statistic :
So, test statistic is 0.986
Answer:
5
Step-by-step explanation:
First you have 24-(5+9)/2
So do 5+9=14
24-14=10
10/2=5
answer is 5

Answer:
f(x) = is the required polynomial.
Step-by-step explanation:
Given the zeroes (roots) of the polynomial are and .
We know that complex roots occur in conjugate pairs.
So, this means that and would also be the roots of the polynomial.
If are to be the roots of the polynomial then the polynomial should have been: .
Now, to determine the polynomial for which would be the roots.
Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.
⇒
⇒
The required polynomial would be the product of all the above polynomials.
Multiply this to get the required equation.
⇒
∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.
