Title: Understanding Sampling Distributions---**Question: Determine the True Statements**Which of the following statements are true?I. The sampling distribution of \(\bar{x}\) has standard deviation \(\frac{\sigma}{\sqrt{n}}\) even if the population is not normally distributed.II. The sampling distribution of \(\bar{x}\) is normal if the population has a normal distribution.III. When \(n\) is large, the sampling distribution of \(\bar{x}\) is approximately normal even if the population is not normally distributed.- [ ] I and II- [ ] I and III- [ ] II and III- [ ] I, II, and III- [ ] None of the above gives the complete set of true responses.**Question Help:** [Message instructor]**Submit Question** Button---**Explanation:**This section is discussing key concepts related to the characteristics of sampling distributions in statistics. The statements explore the conditions under which the sampling distribution of the sample mean \(\bar{x}\) is normally distributed and the role of sample size \(n\) in approximating normality, especially when the population distribution is not normal.**Note:** Concepts like standard deviation, normal distribution, and the central limit theorem (implied in statement III) are foundational in understanding how sample data can infer population parameters.

Assume that two dependent samples have been randomly selected from normally distributed populations. A test of abstract reasoning is given to a random sample of students before and after they completed a formal logic course. The results are given below. Before 74 80 72 80 80 67 93 85 91 77 After 73 80 70 83 78 68 90 82 87 75 Provide a 90% CI on the difference. Round your answers to 3 decimals. Provide negative signs when appropriate. Use leading zeros for values less than 1. Lower Limit: Upper Limit: Based on the results of your CI, what is the conclusion to a two-tailed hypothesis test at alpha = .10? Reject Ho / Do Not Reject Ho Do the results suggest there is a difference in means at alpha = .10? Yes / No

Q. 7 In a study on cholestrol levels a sample of 12 men and women was chosen. The plasma cholestrol levels (mmol/L) of the subjects were as follows: 6.0,6.4,7.0,5.8,6.0,5.8,5,9,6.7,6.1,6.5,6.3,5,8 For what value of k can we say P(X 2k) 20.05 ?
Q. 1In the population, the average score on a test of self-esteem is 50 (σ= 5). You select a randomsample of 25 students who score a mean of 53.a. Shine claims that these students don’t have very high self-esteem, because they are only 3points above the population mean. Why can’t she make this claim merely by looking atthe X? .b. What should she do? .c. What is the z-score for this sample? .d. What conclusion do you draw about your sample? .

ne Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5. Assume that the groups consist of 42 couples. Complete parts (a) through (c) below. nents 1 of nts a.
