2.3 4.0
1. Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.)
2. State the decision rule for 0.05 significance level: H0: μLC ≤ μCK; H1: μLC > μCK. (Round your answer to 3 decimal places.)
3. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
4. Is it reasonable to conclude that Claiborne models earn more? Use the .05 significance level and assume the population standard deviations are not the same.
