Use the file on Blackboard called "Excel Databases.xlsx". Locate the Manufacturer tab. The goal is to test to determine if there is a significant difference between mean Value Added by the manufacturer and the mean Cost of Materials in manufacturing assuming a 1% level of significance. Use Excel to perform the F-test for Equality of Variances at the 1% significance level. Which variable will be Group 1? What can you conclude from running the F-test? O a. Value Added by Manufacturer is Group 1. The F-test concludes that the population variances are unequal. O b. Cost of Materials is Group 1. The F-test concludes that the population variances are equal. OC. Value Added by Manufacturer is Group 1. The F-test concludes that the population variances are equal. O d. Cost of Materials is Group 1. The F-test concludes that the population variances are unequal.
