Question
Answer question number 13,14, and 15.
For items 10-15, refer to this word problem: In one research, the average height of Filipinos is 156.41 cm. Suppose a random sample of 25 Filipino citizens were selected and it was determined that their mean height is 161.2 cm and the standard deviation is 15 cm. Using 0.01 level of signiticance, can it be concluded that the average height of Filipinos has increased? Assume normality over the population. 10. What is the null and alternative hypothesis in the problem above? A. Ho: H = 156.41 Ha: H # 156.41 B. Ho: H = 156.41 Haiu S 156.41 C. Ho: H = 156.41 Ha:H<156.41 D. Ho: μ= 156.41 H4: μ > 156.41 11. What is the level of significance? A. 0.05 B. 0.10 C. 0.01 D. 0.025 12. What test statistic should be used? A. t - test B. z - test C. I D. o 13. Compute the test statistic.
