Question

In a recent global survey across 16 major countries, overeating is cited as the third biggest health concern amid COVID-19 after underexercising and anxiety. The survey also revealed that women are more likely to admit they are overeating compared to men with the biggest gender gap resulting in Canada. A Canadian researcher is interested in finding if the proportion of females aged 25 or over suffering from emotional overeating (P1 ) is higher than the proportion of males suffering from overeating P2 ) as a result of COVID-19. Suppose that 172 out of 1,000 Canadian female respondents aged 25 and over admitted that they were overeating, whereas 90 out of 600 male respondents in the same age group reported that they were overeating a. Which of the following is the correct pair of the null and alternative hypotheses to test if women are more likely to overeat? (Note: Select the number that shows the correct pair) HOP1 - P2 = 0 H1 : P1 P2 <0 HO : P1 - P2 = 0 H1:21 - P270 HO : P1 – P2 = 0 H1P1-P2 > 0 1. 2. 3. b. Select the distribution to use. (Note: Select the number that shows the correct distribution.)
