*Note: For the following problem complete the 5-step process:

Step 1: State the null hypothesis and the alternate hypothesis.

Step 2: Select the level of significance.

Step 3: Evaluate the test statistic.

Step 4: Formulate a decision rule with critical value of test statistic.

Step 5: Compare the test statistic to the critical value and make the decision about H0.

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.

Use the F-Test Two-Sample for Variances to test the hypothesis that the variances between the two methods are the same.Interpret the results.
