Answer:
1) Fail to reject the Null hypothesis
2) We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.
Step-by-step explanation:
A university administrator wants to test if there is a difference between the distance men and women travel to class from their current residence. So, the hypothesis would be:

The results of his tests are:
t-value = -1.05
p-value = 0.305
Degrees of freedom = df = 21
Based on this data we need to draw a conclusion about test. The significance level is not given, but the normally used levels of significance are 0.001, 0.005, 0.01 and 0.05
The rule of the thumb is:
- If p-value is equal to or less than the significance level, then we reject the null hypothesis
- If p-value is greater than the significance level, we fail to reject the null hypothesis.
No matter which significance level is used from the above mentioned significance levels, p-value will always be larger than it. Therefore, we fail to reject the null hypothesis.
Conclusion:
We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.
Answer:
x = -11 and y= -8 is the solution to the system
Step-by-step explanation:
Given:
x - 2y = 5 let it be equation (i)
-x + y = 3 let it be equation (ii)
To find:
x = ?
y = ?
Solution:
The equations are given to us from which we are supposed to find the values of x and y
Taking first equation which is
x - 2y = 5
adding 2y on both sides
x - 2 y + 2y = 5 + 2y
x = 5 +2y ............................(iii)
Now putting this value in equation (ii)
which is
-x + y = 3
Putting value gives
-(5 + 2y) + y = 3
-5 -2y+y = 3
-5 - y = 3
adding 5 on both sides
-5 -y + 5 = 3 + 5
-y = 8
Multiplying both sides by (-1)
-y(-1) = 8 * (-1)
y = -8
Now we have equation (iii) which is
x = 5 + 2y
putting the value of y in it
x = 5 + 2*(-8)
x = 5 -16
x = -11
so the solution to the system is
x = -11 and y= -8
