A researcher studied iron-deficiency anemia in women in each of two developing countries. Differences in the dietary habits between the two countries led theresearcher to believe that anemia is less prevalent among women in the first country than among women in the second country. A random sample of 1900women from the first country yielded 441 women with anemia, and an independently chosen, random sample of 1800 women from the second country yielded461 women with anemia.Based on the study can we conclude, at the 0.01 level of significance, that the proportion p₁ of women with anemia in the first country is less than theproportion P₂ of women with anemia in the second country?Perform a one-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list offormulas.)(a) State the null hypothesis H. and the alternative hypothesis H₁.H₁ :0H₁ :0(b) Determine the type of test statistic to use.(Choose one) ▼(c) Find the value of the test statistic.

A company produces 1,000 blue crayons every day. A sample of 50 crayons are analyzed, and 3 of them are found to not meet the standards of the company, so they are labeled defective. A simulation is run in which 50 crayons are chosen out of 1,000 so that each crayon chosen has a 6% chance of being defective. The simulation is run 500 times, and the mean proportion of defective crayons is 0.059 with a standard deviation of 0.012. What is a good margin of error based on this simulation? Based on a population proportion estimate and margin of error, is 0.07 a plausible value for the population proportion of crayons that are defective? Explain your reasoning.
5 to 10 grams or more of soluble fiber a day decreases your LDL cholesterol according to Mayo Clinic. A cereal manufacturer 'Healthy Goals' claims that their high fiber cereals help reduce the LDL numbers among 76% people who eat 'Healthy Goals' cereals. In a random sample of 65 people who eat cereals made by 'Healthy Goals' 44 reported their LDL cholesterol numbers being lowered. Based on this sample is the claim made by the company that 76% lower their LDL really true?" Do necessary calculation and answer the question. Do not simply put down yes/no answers.

Should there be a significant difference with this study, what post-hoc test shall be used? Dr. Hess has done work that suggests that emotional arousal affects pupil size. To ascertain if the type of arousal makes a difference, you decided to measure pupil size under three different arousal conditions (Neutral, Pleasant, Aversive). Each participant will look at all the different pictures that differ according to the condition. The pupil size after viewing each photograph is measured in millimeters. * t-Test paired two sample for means O t-Test assuming equal variances O t-Test assuming unequal variances
Determine whether the results appear to have statistical significance, and also determine whether theresults appear to have practical significance: Bias in Jury Selection In the case of Casteneda v. Partida, it was found that during a period of 11 years in Hidalgo County, Texas, 870 people were selected for grand jury duty, and 39% of them were Americans of Mexican ancestry. Among the people eligible for grand jury duty, 79.1% were Americans of Mexican ancestry.Please explain it step by step, thank you.

Oishi and Schimmack (2010) report that people who move from home to home frequently as children tend to have lower than average levels of well-being as adults. To further examine this relationship, a psychologist obtains a sample of n = 12 young adults who each experienced five or more different homes before they were 16 years old. These participants were given a standardized well-being questionnaire for which the general population has an average score of = 40. The sample of well-being scores had an average of M = 37 and a variance of s2 = 10.73. a. compute cohens d
