A researcher is interested in seeing if the average income of rural families is different than that of urban families. To see if his claim is correct he randomly selects 60 families from a rural area and finds that they have an average income of $68941 with a population standard deviation of $541. He then selects 57 families from a urban area and finds that they have an average income of $67583 with a population standard deviation of $678. Perform a hypothesis test using a significance level of 0.05 to test his claim. Let rural families be sample 1 and urban familis be sample 2. The correct hypotheses are:
