Suppose you are an expert on the fashion industry and wish to gather information to compare the amount earned per month by models featuring Liz Claiborne attire with those of Calvin Klein. The following is the amount ($000) earned per month by a sample of 15 Claiborne models: $3.9 4.5 $4.2 $5.1 $5.9 $6.4 $6.6 $6.4 $5.5 $3.8 $4.5 6.9 3.7 5.0 6.7 The following is the amount ($000) earned by a sample of 12 Klein models. $4.6 $4.2 $5.2 $5.1 $4.8 $3.9 $4.0 $4.2 $3.6 $3.9 4.3 4.4 B Click here for the Excel Data File Is it reasonable to conclude that Claiborne models earn more? Assume the population standard deviations are not the same. a. Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.) Degrees of freedom b. State the decision rule for 0.10 significance level: Hg: Hclaiborne S Hcolvin Klein : Hz: H cləiborne H colvin Klein: (Round your answer to 3 decimal places.) Reject Ho if t> c. Compute the value of the test statistic. (Round your answer to 3 decimal places.) Value of the test statistic
