Answer the ff. For items 10-15, refer to this word problem: In one research, the average height of Filipinos is156.41 cm. Suppose a random sample of 25 Filipino citizens were selected and it was determinedthat their mean height is 161.2 cm and the standard deviation is 15 cm. Using 0.01 level ofsigniticance, can it be concluded that the average height of Filipinos has increased? Assumenormality over the population.10. What is the null and alternative hypothesis in the problem above?A. Ho: H = 156.41 Ha: H # 156.41B. Ho: H = 156.41 Haiu S 156.41C. Ho: H = 156.41 Ha:H<156.41D. Ho: μ= 156.41 H4: μ > 156.4111.
