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 50 families from a rural area and finds that they have an average income of $69532 with a population standard deviation of $916. He then selects 49 families from a urban area and finds that they have an average income of $65446 with a population standard deviation of $716. Perform a hypothesis test using a significance level of 0.10 to test his claim. Let rural families be sample 1 and urban familis be sample 2. The correct hypotheses are: O Ho: µ1 < M2 HA: 41 > µ2(claim) O Ho: µ1 2 H2 HA: H1 < µ2(claim) O Ho:µ1 = M2 HA: H1 # µ2(claim) Since the level of significance is 0.10 the critical value is 1.645 and -1.645 The test statistic is: (round to 3 places) The p-value is: (round to 3 places)
