Here are the IQ test scores of a sample of 12 seventh-grade girls in a Midwestern school district:

1. What are the mean and standard deviation of these IQ scores?

2. What proportion of the scores is within one standard deviation of the mean? What proportion of the scores is within two standard deviations of the mean?

3. What would we expect the proportions in part (b) to be if the scores followed a Normal distribution?

4. Is the true distribution of scores close to a Normal distribution or not? In your opinion, would it be reasonable to claim that IQ test scores follow a Normal distribution?

case study
Julie is 45 year old mother and lives on a cropping farm, run as a family business, with her husband and his brother. Julie has three children same, aged 14; Katie, aged 12 and James aged 8.The two older children attend boarding school and return home for holidays. James is at home and attends the local primary school 50 km away.
Both Julie's boys have type 1 diabetes that she manages.
Julie has lived with her diabetes for 37 years and has many comorbidities due her both her diabetes and celiac disease. which she developed as a teenager. Julie has stage 3 chronic kidney disease, poor eyesight and osteoporosis. She is currently tryinģ to give up smoking after having smoked since of 16.
Julie currently sees her endocrinologist in large metropolitan hospital every three-month at outpatient clinic. It take her five hours to drive by car to the appointment in the city a journey that she takes with her husband. Her nephrologist is based at the regional hospital about 2 hours drive from home.Julie engages with a diabetes educator via phone and face to face monthly . The local hospital is 50 km away and is small, rural hospital. with a locum doctor and regular nursing staff, who cover the acute inpatient ward, and community registered nurse. She attends a community chronic diseases self management program at the local church hall run by the community registered nurse once a week in town and does her weekly groceries. Julie has expressed to the diabetes educator that she need more assistance with managing her own condition. She is concerned that her son who have type 1 diabetes, may end up with the same comorbidities as her because she has an autoimmune chronic condition

Question
identify 5 evidence based nursing intervention that are appropriate to implement in planning the patient's nursing care and provide a clear rationale for each intervention

1. Consider a college town where the initial price of rental apartments is $500 and the initial quantity is 3,000 apartments. The price elasticity of demand for apartments is 1.25, and the price elasticity of supply of apartments is 0.75.

1. Use demand and supply curves to show the initial equilibrium, an label the equilibrium point a.
2. Suppose that an increase in college enrollment is expected to increase the demand for apartments in the college town by 30 percent. Use your graph to show the effects of the increase in demand on the apartment market. Label the new equilibrium point b.
3. Predict the effect of the increase in demand on the equilibrium price of apartments.
4. Find the new equilibrium quantity given the new price.

Suppose that a small town has six burger shops whose respective shares of the local market are (as percentages of all hamburgers sold): 26%, 20%, 18%, 14%, 12%, 10%,

a) What is the four-firm concentration ratio of the hamburger industry and what is the Hirchmann Herfindahl Index (HHI) for the hamburger industry in this town?                                                                      

b) Assume that the largest producer now purchases the third largest firm (based market share) so that this new combined firm has the same market share as old firm 1 and old firm 3 combined. Compute the new four-firm concentration ratio and to the new HHI?

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 44 couples. Complete parts A to C below.

a. Find the mean and the standard deviation for the numbers of girls in groups of 44 births.

b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.

value of _____ girls are significantly low.

value of _____ girls are significantly high.

c. Is the result of 41 girls a result that is significantly​ high? What does it suggest about the effectiveness of the​ method?

The result ____ (is / is not) significantly high, because 41 girls is __________ (equal to, greater than, less than) ___ (specific number) girls. A result of 41 girls would suggest that the method ________ (is effective/ is not effective)

Marginal tax rates were cut substantially during the 1980s, and although rates were increased in the early 1990s, the marginal rates applicable in the highest income brackets were still well below the top rates of the 1960s and 1970s. How did the lower rates of the 1980s and 1990s affect the share of taxes paid by high income taxpayers? Were the lower rates of the 1980s and the 1990s good or bad for the economy?

A woman plans to bear three children. The probability of having a boy is 50%. Out of the three childer she bears, determine:
a) Mean number of boys (using the formula) (Ans: 1.5)
b) Standard Deviation of the number of boys (using the formula) (Ans: 0.866)
c) Sketch the density function of the number of boys and comment on whether the mean and standard deviation in parts a and b are plausible. (Ans: P={0.125 0.375 0.375 0.125} for 0, 1, 2, and 3 respectively)
d) Sketch the distribution function of the number of boys.

The mayor of a town has proposed a plan for the annexation of a new community. A political study took a sample of 1600 voters in the town and found that 68% of the residents favored annexation. Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is over 65% . Determine the P-value of the test statistic. Round your answer to four decimal places.

Do not use global variables.

Note : The interleave function should not accept input or display any output. The function should work with any size strings.

Caution : Inclusion of unnecessary or unrelated logic or code segment will result in loss of points.

Write C a program that has a main function and a utility function called merge. The main function should prompt the user to enter one short string (no longer than 20 characters) and hard code another string with value "123456" (this could be anything, not exceeding 20 characters). It should call the merge function that will interleave the first string and the second string to produce a third string. The merge stops with the shortest string. The main program should print out all the three strings after the function call.

Use as many variables and arrays as needed.

Expected input/output: ( do not worry about the exact number of blank lines in the output)

Scenario 1

Enter string 1 : ABCDE

Merged Result

String 1 : ABCDE

String 2 : 123456

Merged string : A1B2C3D4E5

Scenario 2

Enter string 1 : ABCDEFG

Merged Result

String 1 : ABCDEFG

String 2 : 123456

Merged string : A1B2C3D4E5F6
