Question 15 (4 points) Two researchers estimated the mean energy intake of American adults during 2009- 2010, which is 2195 kcal/day. You think there has been a change of pattern since 2019-2020 in that the mean energy intake might have increased by then. To verify this, you decided to conduct a test of significance at = 0.05. [Source: Ford, E. S., & Dietz, W. H. (2013). Trends in energy intake among adults in the United States: findings from NHANES. The American journal of clinical nutrition, 97(4), 848-853. https://doi.org/10.3945/ajcn.112.052662] From your random sample of 45 male and female American adults, the sample mean is calculated to be 2225 kcal/day, with a standard deviation of 72 kcal/day. Which of following is the most appropriate null and alternative hypotheses? A) Ho : = 2195 vs H : HA 2195 ) : < 2195 vs HA : > 2195 c) Ho: 2195 vs H: > 2195 D) Ho2225 vs HA > 2225 E) Ho 2225 vs HA > 2225 : Question 16 (4 points) According to a World Health Organization (WHO) report, the global prevalence of anemia among pregnant women is 40%. You suspect that it might be higher for one particular district. Conducting a test of significance ( = 0.05) with the hypotheses Ho: p 0.4 vs Ha: p > 0.4, you failed to reject the null hypothesis. If the true percentage of anemia in pregnant women in the district is 61%, did an error occur? If so, what type of error is it? [Source: Toteja, G. S., Singh, P., Dhillon, B. S., Saxena, B.
