Answer:
Test statistic Z= 0.13008 < 1.96 at 0.10 level of significance
null hypothesis is accepted
There is no difference proportion of positive tests among men is different from the proportion of positive tests among women 
Step-by-step explanation:
<em>Step(I)</em>:-
Given surveyed two random samples of 390 men and 360 women who were tested
first sample proportion 
                     
second sample proportion
                   
Step(ii):-
Null hypothesis : H₀ : There is no difference  proportion of positive tests among men is different from the proportion of positive tests among women
Alternative Hypothesis:-
There is difference between proportion of positive tests among men is different from the proportion of positive tests among women
  

where
           
          P =  0.920

Test statistic Z =  0.13008
Level of significance = 0.10
The critical value Z₀.₁₀ = 1.645
Test statistic Z=0.13008 < 1.645 at 0.1 level of significance 
Null hypothesis is accepted 
There is no difference proportion of positive tests among men is different from the proportion of positive tests among women 
 
 
        
             
        
        
        
Answer:
The answer is 10 and 37 degrees.
Step-by-step explanation:
Triangle angles add up to 180.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. thank you and have a nice day!
 
        
             
        
        
        
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80
        
             
        
        
        
Answer:
x=12
Step-by-step explanation:
9x-14=2(3x+11)
9x-14=6x+22
9x-6x=22+14
3x=36
x=36/3=12
 
        
             
        
        
        
Answer:
12
Step-by-step explanation:
 x/2+4=10
-4          -4
________
x/2=6
(2/1)*(x/2)=(2/1)*(6)
________
x=12
