Part B A random sample of 25 arnis sticks showed an average of 192.4 cm with a standard deviation of 16.7 cm. Is this in line with the manufacturer's claim of an average length of 200 cm, using a = 0.05 level of significance? 11. The null hypothesis is u = 192.4 12. The alternative hypothesis is u # 200. 13. u = 200 14. The sample mean is 192.4 15. The critical value is the boundary between the rejection region and non-rejection region. 16. Used z-test, one-tailed. 17. The computed value is -2.29 18. The critical value to be used is -1.711 19. The decision is REJECT the Ho. 20. The average length of an arnis is 200 cm
