Answer:
You get $5727.27
Step-by-step explanation:
At the start, you have 2000
After you are attacked, stampeded and have trouble finding water, you have lost 10% of your cattle
2000 * 10% is 200
2000 - 200 is 1800
Multiply 1800 cattle by $35 per cow
1800 * $35 = $63000
10 cowboys + 1 (you) is 11 people
Divide $63000 by 11
63000 / 11 = $5727.27
You get $5727.27
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
