30. Northwest Atlantic Cod. Researchers M. Kroll et al. studied the influence of paternity on rates of mortality and development in eggs and larvae of Northwest Atlantic cod in the article, “Paternal Ef- fects on Early Life History Traits in Northwest Atlantic Cod, Gadus morhua" (Journal of Applied Ichthyology, Vol. 29, Issue 3, pp. 623– 629). A sample of adult male Northwest Atlantic cod was collected in Nova Scotia, Canada. The following table gives the lengths, in cen- timeters (cm), of the cod sampled. 47.6 65.1 54.6 48.5 58.6 67.9 48.1 62.5 52.4 55.4 57.1 55.8 a. Using Table III in Appendix A, construct a normal probability plot of the given data. b. Use part (a) to identify any outliers. c. Use part (a) to assess the normality of the variable under consid- eration.
“A researcher wants to examine the effects of siblings on the amount of annual salary people earned when they are 35 years old. Salary data of three groups of 35-year olds were collected and are presented here. 4 participants with no sibling while growing up (n1 = 4): 50K, 51K, 49K, 50K. 5 participants with 1 to 2 siblings while growing up (n2 = 5): 55K, 56K, 54K, 58K, 52K. 4 participants with 3 and more siblings while growing up (n3 = 4): 60K, 60K, 70K, 50K. The researcher calculated: ∑x2 = 39747, G2/N = 39325, ∑T2/n = 39525.” Do the data indicate significant differences among the three groups of 35-year olds? Test at the alpha = .05 level. a. No, the calculated F value was not larger than the critical F value; results were not statistically significant and fail to reject the null hypothesis. b. Yes, the calculated F value was not larger than the critical F value; results were not statistically significant and fail to reject the null hypothesis. c. Yes,…
In the article “The Eastern Cottonmouth (Agkistrodon piscivorus) at the Northern Edge of Its Range” (Journal of Herpetology, Vol. 29, No. 3, pp. 391–398), Blem and Blem examined the reproductive characteristics of the eastern cottonmouth, a once widely distributed snake whose numbers have decreased recently due to encroachment by humans. A simple random sample of 44 female cottonmouths yielded a sample mean of ??̅ = 7.6 young per litter. Assume σ = 2.4. a. Is the sample mean likely to equal μ exactly? Explain your answer b. Find the 95% Confidence Interval. c. How large a sample would be needed to get at 99% confidence interval with a margin of error of just 0.1?
We are interested in comparing the proportions of men and women who say earning a large salary is very important to them. You surveyed 200 men and 200 women and recorded their answers to the question as “yes” (earning a large salary is very important) or “no” (earning a large salary is not very important). Yes No Total Men 150 50 200 Women 110 90 200 Total 260 140 400 Test the association between sex and the importance of earning a large salary using a z-test. Provide the null and alternative hypotheses, test statistic, p-value, and conclude test with 0.01 signifigance.
1. According to the Civil Code of the Philippines, the marriageable age of Filipinos is 18. A researcher found out that the average age of Filipinos who got married is 23 years old. A random sample of 25 married couples were taken. Is there a reason to believe that the sample is significantly younger that the others in getting married at 1% level of significance? (the output range should be at cell G4) 25, 28, 30, 32, 31, 32, 28, 28, 20, 20, 21, 22, 23, 23 , 22, 21, 20, 26, 26, 29, 30, 29, 30, 24, 24
You also conducted a review of the research literature and found that similar studies examining the relationship between alcohol consumption and liver cancer found the following: Smithson et al. RR 3.3 (95% CI:1.95-5.20) Ribera et al. RR 2.1 (95% CI:1.17-3.33) Gonzalez et al. RR 2.75 (95% CI 2.26-3.45) Which one of Hill’s criteria does this illustrate? Explain.
