Your answer is 
B) 1/2
because there are 5 odd and 5 even numbers from 5 through 10, so it would be 1/2.
Glad I could help, and good luck!
        
                    
             
        
        
        
Answer:
The test statistic is t = 3.36.
Step-by-step explanation:
You're testing the claim that the mean difference is greater than 0.7. 
At the null hypothesis, we test if it is 0.7 or less, that is:

At the alternate hypothesis, we test if it is greater than 0.7, that is:

The test statistic is:

In which X is the sample mean,  is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
 is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
0.7 is tested at the null hypothesis:
This means that 
Survey of 35 people. From the sample, the mean difference was 0.95, with a standard deviation of 0.44.
This means that 
Calculate the test statistic



The test statistic is t = 3.36.
 
        
             
        
        
        
Answer: 22
Step-by-step explanation:
I’m not sure if hats number  is a 5.50 but if it is the answer would be 22 I think ^^  I might be wrong?
 
        
             
        
        
        
Area = (base)*(height)
15 = (x+7)(x-7)
(x+7)(x-7) = 15
x^2 - 49 = 15
x^2 - 49+49 = 15+49
x^2 = 64
sqrt(x^2) = sqrt(64)
x = 8 ... note that x can't be negative
If x = 8, then the base is...
x+7 = 8+7 = 15
Therefore the base is 15 units. 
(the height is x-7 = 8-7 = 1 unit)
