#1)  An researcher  wishes to see if the primary way people obtain information is independent of their highest level of education. A survey of 400 high school and college graduates yielded the following information. At the a = 0.05 significance level, test the claim that the way people obtained information is independent of their education level.

Part 1: Choosing a study type. What is the best way to answer each of the following questions: an experiment, a sample survey, or an observational study that is not a sample survey? Be sure to provide a detailed explanation for each of your choices. a) Do employees who listen to music while they are working perform better in their job tasks than those employees who do not listen to music while working? b) Is your favorite sports team penalized more during away games than during home games? c) Are high school graduates satisfied with the diversity of jobs available to them straight out of high school?

The nurse is preparing to do a health history and physical assessment on a 5-year-old child whose family has just moved to the area.

1. What is the appropriate introduction when first meeting the family?

2.   List 6 guidelines for communicating with children.

3.   Communication is related to the development of thought processes in children-the nurse communicates at the level the child understands. What are the thought processes of the school-age child?

4. What are the 10 categories that are addressed in a pediatric health history?

5. What are the developmental characteristics of a school-age child’s response to pain? What tool would you use to evaluate pain in this age child?

Lionel is an unmarried law student at State University Law School, a qualified educational institution. This year Lionel borrowed $27,000 from County Bank and paid interest of $1,620. Lionel used the loan proceeds to pay his law school tuition. Calculate the amounts Lionel can deduct for higher education expenses and interest on higher-education loans under the following circumstances:

a. Lionel's AGI before deducting interest on higher-education loans is $50,000.

b. Lionel's AGI before deducting interest on higher-education loans is $79,000.

c. Lionel's AGI before deducting interest on higher-education loans is $90,000.

In a high school orchestra there are 3 training groups: one is Violin, one in Flute, and one in Cello. These sections are open to any of the 100 students in the school. There are 36 students in the Violin group, 30 in the Flute group, and 27 in the Cello group. There are 9 students that are in both Violin and Flute, 18 that are in both Violin and Cello, and 6 are in both Flute and Cello. In addition, there are 4 students taking all 3 sections. If a student chosen at random,

a) the probability that he is not included in any of these groups is?

b) the probability that he is playing exactly one instrument group is?

c) When two people are chosen randomly, the probability that at least 1 is in an instrument group is?

A student with an eight​ o'clock class at a university commutes to school by car. She has discovered that along each of two possible routes her traveling time to school​ (including the time to get to​ class) is approximately a normal random variable. If she uses the highway for most of her​ trip,μ=22 minutes and σ=5 minutes. If she drives a longer route over city​ streets, μ=26 minutes and σ=33 minutes. Which route should the student take if she leaves home at ​7:30 ​A.M.? (Assume that the best route is one that minimizes the probability of being late to​ class.)

The following data represent the highest level of education and belief in Heaven for a random sample of adult Americans.

1. Construct a relative frequency marginal distribution.

2. What proportion of adult Americans in the survey definitely believe in Heaven?

3. Construct a conditional distribution of belief in Heaven by level of education.

4. Draw a bar graph of the distribution found in part (c).

An organization surveyed 617 high school seniors from a certain country and found that 327 believed they would not have enough money to live comfortably in college. The folks at the organization want to know if this represents sufficient evidence to conclude a majority​ (more than 50​%) of high school seniors in the country believe they will not have enough money in college.

​(a) If the researcher decides to test this hypothesis at the alpha (α) equals=0.05 level of​ significance, compute the probability of making a Type II​ error, beta β​, if the true population proportion is 0.56. What is the power of the​ test?

​(b) Redo part​ (a) if the true population proportion is 0.59.

In a survey of 176 females who recently completed high​ school, 75​% were enrolled in college. In a survey of 180 males who recently completed high​ school, 65​% were enrolled in college. At alpha equals 0.09​, can you reject the claim that there is no difference in the proportion of college enrollees between the two​ groups? Assume the random samples are independent. Complete parts​ (b) through​ (e). ​(b) Find the critical​ value(s) and identify the rejection​ region(s). ​(c) Find the standardized test statistic. ​(d) Decide whether to reject or fail to reject the null hypothesis. ​(e) Interpret the decision in the context of the original claim.

A statistics student wondered whether there might be a relationship between gender andcommuting methods among students at a high school. He surveyed 200 the high school students (92 males and 108 females) he happened to encounter around campus, asking each of them about their typical way of commuting to the college. The data from this survey appears below:

1. List the appropriate conditions for this test and explain why each has (or has not) been satisfied:

2. Compute the P-value for this test

3. State an appropriate conclusion for this test
