see picture for correct answer
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
i feel like its D, i apologize if im wrong though.
Mathematically written:
3 * x + 7 = 25
3x + 7 = 25
3x = 25 - 7
3x = 18
x = 18 / 3
x = 6
Proof:
3 * 6 + 7 = 25
18 + 7 = 25
25 = 25 → both sides of the equation are equal, our answer is correct
Notes:
A number - Is an unknown number, called a variable, which in this case is substituted by the letter x.
