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:
B
Step-by-step explanation:
The exterior angle is the sum of the two given angles. (The are called the remote interior angles. The are not connected to the exterior angle we are supposed to find.)
exterior angle = 44 + 39
exterior angle = 83
Answer:
Step-by-step explanation:
Step-by-step explanation:
By taking ( x = 18°)
<u>L.H.S</u>
cos(3x)=sin(2x)
cos(3x) = cos( 3X18°)= cos (54°)
= cos[ 90° - (2x18°)] ∵[ 90°- (2x18°) = 54°]
= ∴ sin ( 2x18°)
As (x = 18°)
= sin (2x) = R.H.S
