Based on the data from question 8, for testing if first-borns population (group 1) have a larger mean IQ compared to later-borns(group 2) using the two-sample t-test, what is the null hypothesis and alternative hypothesis?A) H_0: μ_1=u_2, H_A: μ_1>u_2BH_0: _1>μ_2, H_A: µ_1=µ_2CH_0: μ_1-p_2, H_A: μ_1 p_2(D) H_0: μ_1=H_2, H_A: μ_1<μ_2 Use the following data to answer question 8 - 12. A number of studies have claimed evidence that the first-born in a family is, onthe whole, more likely to be "successful" than later-borns. A study along this direction compared the IQs of a random sample of 80first-borns with those of an independent random sample of 105 later-borns. The data are summarized below:Sample sizeSample meanSample SDFirst-borns801127.2Later-borns1051088.0

as per guideline expert have to solve first question only .

Conduct a two-factor ANOVA to examine the effects of 'maternal diet' (‘diet’: No alcohol, vs. alcohol) and age (adolescent rat vs. adult rat) on passive avoidance (‘pa’). State the three alternative hypotheses in words. State the alternative hypothesis of the interaction in terms of whether the effects of maternal diet (alcohol vs. not alcohol) on passive avoidance depend on the levels of age (i.e., on whether the rat is an adolescent or an adult rat).
Select a significance level α and reject the null-hypothesis if the p-value is less than α. Explain, in complete sentences, your findings: Is there a statistically significant association (at α level) between the provided genes? What is the magnitude and the direction of the association?

An aerosolized vaccine for measles was developed in Mexico and has been used on more than 44 million children since 1980. Aerosolized vaccines have the advantages of being able to be administered by people without clinical training and do not cause injection‑associated infections. Despite these advantages, data about efficacy of the aerosolized vaccines against measles compared to subcutaneous injection of the vaccine have been inconsistent. Because of this, a large randomized controlled study was conducted with children in India. The primary outcome was an immune response to measles measured 91 days after the treatments. Among the 785 children receiving the subcutaneous injection, 743 developed an immune response, while among the 775 children receiving the aerosolized vaccine, 662 developed an immune response.
