The mean annual family income for 19 people making inquiries at the first development is $160,000, with a standard deviation of $37,000. A corresponding sample of 27 people at the second development had a mean of $181,000, with a standard deviation of $32,000. Assume the population standard deviations are the same. At the 0.01 significance level, can Fairfield conclude that the population means are different? a. State the decision rule for 0.01 significance level: Ho: H1 H2; H1 H1 H2. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Reject HO if t is not between and 5. Compute the value of the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) Value of the test statistic (5.96) Fairfield Homes is developing two parcels near Pigeon Forge, Tennessee.
