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

Answer:
16.2 foot shadow
Step-by-step explanation:

x = 486 / 30
x = 16.2
