1.F-Test Two-sample for Variances
Use Excels 2-sample variances data analysis tool to solve the following problem.A well-known ice cream store wants to test two different methods for scooping ice cream so they can use the one that has the least variability in their training of new and current employees.It took a sample of the ice cream cones scooped and measured the weights.
