\fTwo 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 a = 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? O A) HO : M 2195 O B) HO : M = 2195 us HA : M / 2195 OC) HO : x 2225 OD) HO : T 2195 O E) HO : M 2225Question 11 (4 points) The following table shows the observed counts from the distribution of 149 males and females born preterm and full-term. The figures below came from a study by Harel-Gadassi et al.(2018) regarding the long-term risks of autism spectrum disorder (ASP) in children born preterm (PT) and full term (FT). Birth Type Gender Pre-term Full-term Total (PT) (FT) Female 63 21 84 Male 47 18 65 Total 110 39 149 [Source: Harel-Gadassi, A., Friedlander, E., Yaari, M., Bar-Oz, B., Eventov-Friedman, S., Mankuta, D., & Yirmiya, N.

Autism research and treatment, 2018, 8316212. https://doi.org/10.1155/2018/8316212] Suppose you are interested in determining if an association exists between gender and birth type. Conducting a test of significance under 5% level of significance, you calculated the p-value to be equal toQuestion 12 (4 points) You perform a test of significance, using the hypotheses \"(FF S 5vs. \"41;! > 5. Based on a sample of size 11, you obtain a test statistic of 1.19. What will be your p-value and decision at 5% level of significance? 0 A) p-value > 0.2 O B) 0.1
