Answer:
H0: μ1 = μ2
H1: μ1 ≠ μ2 ;
xbar1 - xbar2
Step-by-step explanation:
The Null hypothesis should state that there is no difference in average household income between those located east and west of the Mississippi
H0: μ1 = μ2
H1: μ1 ≠ μ2
Statistic from the sample that would be used to estimate difference
Statistic refers to the numerical characteristic derived from the sample.
To estimate the difference in the average household income between those located east and west of the Mississippi, we take the sample mean of the two groups
Group 1, East of Mississippi = xbar 1
Group 2, West of Mississippi River = xbar 2
xbar1 - xbar2
Y=-x
(X,Y) will change to -> (-y,-x)
(5,-3) will change to ->(3,-5)
-3 changed to 3 because -(-3) = 3
So the answer is (3,-5). I recently learn about this one too.
Hey there!
Let's make one and solve it.
Fraction division is solved by using a simple rule:
"keep, switch, flip!"
So if we have:
4/8 divided by 5/9
We keep the 4/8, switch the division to multiplication, and flip the 5/9 to 9/5:
4/8 * 9/5 = 36/40 = 18/20 = 9/10
Hope this helps!
Answer:
x = 1/3
There is one solution
Step-by-step explanation:
3x -1= 1-3x
Add 3x to each side
3x+3x -1= 1-3x+3x
6x-1 =1
Add 1 to each ide
6x-1+1 = 1+1
6x =2
Divide each side by 6
6x/6 = 2/6
x = 1/3
There is one solution
