A random sample of 30 Georgia residents provided a mean income of $46,000 earned last year. Another sample from Ohio residents showed a mean income of $43,000 during the same period. At the population level, using Georgia as population 1 and Ohio as population 2, did Georgia residents earn a higher income compared to the Ohio ones last year?

The hypotheses are:

Question 3 options:

a)
