3. Scientists researching the effect of dietary supplements such as multivitamins and supplements of folic acid, magnesium or zinc on the health of elderly women followed 38,772 women, whose average age was 62 at the start of the study, over a period of 19 years and recorded the death rates of those who did and did not use dietary supplements. The researchers found that women using supplements were more likely than women who did not to have died during that period. Write the hypotheses for testing if the death rate of elderly women who use dietary supplements is different than the death rate of elderly women who do not use dietary supplements. Ho: Hused = Hnoi HẠ: Hused* Hnot O Ho :Pused =pnoti HA:Pused> Pnot Ho : Pused = Pnoi HA: Pused + Pnot Họ: Pused = Pnoi HA: Pused * Pnot Incorrect This question revisits the setup of hypothesis testing within the categorical data / proportions. u should not appear in the hypothesis because we use that notation for the mean of a numerical variable, not for proportions (calculated for categorical variables).
