Test whether the Lamar County yield variance is greater than the yield variance for Hale County at an alpha level of 0.05. Use the Excel data analysis function to perform your tests? Hint, think about the test and then look at the variance values. Hint 2, for this class the data with the largest variance will be the numerator. This makes a right-tailed test, that will be used throughout the class as we move to OLS. Sub-questions 4.1 What is the null hypothesis? 4.2 What is the alternative hypothesis? 4.3 By hand or using Excel draw the F-distribution labeling, the critical values rejection and fail to reject regions, the calculated f-statistic. 4.4 Do you fail to reject or reject the null hypothesis
