A physiologist researches average 5K-race time for normal people and compares the average time between men and women. With this result, the researcher confirms her hypothesis and could expand her research for other purpose using specific gender. 12. Suppose we evaluate her scientific hypothesis that male 5K-race time is faster than female 5K-race time on average. State your null hypothesis and alternative hypothesis. Ho : Ymen = Ywomen Versus HA : Ymen # Ywomen Normal (b) Ho : Hmen = Pwomen Versus HA : Hmen Hwomen- Ho : Ymen = Ywomen Versus HA : Ymen
