A researcher is interested in seeing if the average income of rural families is less than that of urban families. To see if his claim is correct he randomly selects 23 families from a rural area and finds that they have an average income of $69963 with a standard deviation of $769. He then selects 23 families from a urban area and finds that they have an average income of $68783 with a standard deviation of $571. Perform a hypothesis test using a significance level of 0.05 to help him decide. Let the rural families be sample 1 and the urban families be sample 2. The correct hypotheses are:
