Question 11 (Bonus) (4 points) Saved 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. (2018). Risk for ASD in Preterm Infants: A Three-Year Follow-Up Study. 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. What are the expected counts of males born pre-term and full-term? A) Expected p = 47; Expected FT = 18 B) Expected pT = 37.25; Expected FT = 37.25 C) Expected pT = 62.0134; Expected FT = 21.9866 D) Expected pT = 47.9866; Expected FT = 17.0134 E) Expected p = 110; Expected FT = 39 Question 13 (4 points) Saved You perform a test of significance, using the hypotheses Ho: 55 VS. HAN >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? A) p-value>0.2 B) p-value 0.963, fail to reject the null hypothesis C) 0.1 < p-value < 0.2, reject the null hypothesis D) 0.025
