The marketing manager of a large multinational corporation is concerned that some salespersons perform very well and others quite poorly. To help analyze the problem he draws a random sample of 20 salespersons, determines their commission incomes, and calculates the following statistics: x = $37.2, and s = $7.6. Use a=0.05 to test whether the population variance exceeds $35. Ho: o² ≤ 35 Ha: o² > 35 test statistic is • Reject Ho if x² >. Conclusion:
