Michael Smith would like to open a new charter grade school and is considering Berks County or Chester County as possible locations. The annual household incomes in each county are a factor. Michael collected a random sample of household incomes for both counties.

They are as follows (in thousands of dollars) and can also be found in the Excel file charter school.xlsx.

Berks County ($) Chester County ($) 59.8 40.7 86.7 31.4 35.8 62.9 100.4 94.8 80.6 67.7 87.7 48.6 45.0 76.5 38.8 Perform a hypothesis test using a = 0.05 to determine if there is a difference in annual household incomes between these two counties.
