2.Formulate or establish the alternative hypothesis (Ha).

3.Determine the type of test.

4.Determine the level of significance / degrees of

freedom.

5.Determine the appropriate test statistic.

6. Select the appropriate formula.

7. Calculate the test statistic value.

8. Determine the tabular or critical value.

9. State the decision.

10. Make the statistical conclusion.

WORKSHEET#10 USE THE TENSTEP PROCESS OF TESTING HYPOTHESIS The manager of a department store claims that the average cost of a pair of rubber shoes for teens is Php 4,500.00. A random sample of 50 pairs of shoes has an average cost of Php 4,200.00 with an assumed population standard deviation of Php 150.00. At 0.05 level of significance, is there enough evidence to reject the manager's claim? Computed Value: Tabular Value: 1. Ho: 2. Ha: 3. Type of Test: 4. Level of Significance / Degrees of Freedom: 5. Test Statistics: 6. Formula: 7. 8. 9. Decision: 10. Conclusion
