Is college worth it? Among a simple random sample of 331 American adults who do not have a four-year college degree and are not currently enrolled in school, 131 said they decided not to go to college because they could not afford school.

NOTE: While performing the calculations, do not used rounded values. For instance, when calculating a p-value from a test statistic, do not use a rounded value of the test statistic to calculate the p-value. Preserve all the decimal places at each step.

Enter at least 4 decimal places for each answer in WeBWorK.

1. A newspaper article states that only a minority of the Americans who decide not to go to college do so because they cannot afford it and uses the point estimate from this survey as evidence. What are the correct hypotheses for conducting a hypothesis test to determine if these data provide strong evidence supporting this statement?

A. ?0:?=0.5H0:p=0.5, ??:?>0.5HA:p>0.5
B. ?0:?=0.5H0:p=0.5, ??:?<0.5HA:p<0.5
C. ?0:?=0.5H0:p=0.5, ??:?≠0.5HA:p≠0.5

2. Calculate the test statistic for this hypothesis test.  ? z t X^2 F  =

3. Calculate the p-value for this hypothesis test.

4. Based on the p-value, we have:
A. some evidence
B. extremely strong evidence
C. little evidence
D. very strong evidence
E. strong evidence
that the null model is not a good fit for our observed data.

The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

Assignment #8: Chi-Square Test of Independence Directions:

Use the Crosstabs option in the Descriptives menu to answer the questions based on the following scenario. (Be sure to select Chi-square from the Statistics submenu and Observed, Expected, Row, and Column in the Cells submenu. Assume a level of significance of .05)

The school district recently adopted the use of e-textbooks, and the superintendent is interested in determining the level of satisfaction with e-textbooks among students and if there is a relationship between the level of satisfaction and student classification. The superintendent selected a sample of students from one high school and asked them how satisfied they were with the use of e-textbooks. The data that were collected are presented in the following table.

Student Classification (N = 126)

Satisfied Freshmen Sophomore Junior Senior

Yes 13 13 21 20

No 22 17 8 12

1. Of the students that were satisfied, what percent were Freshmen, Sophomore, Junior, and Senior? (Round your final answer to 1 decimal place).

2. State an appropriate null hypothesis for this analysis.

3. What is the value of the chi-square statistic?

4. What are the reported degrees of freedom?

5. What is the reported level of significance?

6. Based on the results of the chi-square test of independence, is there an association between e-textbook satisfaction and academic classification?

7. Present the results as they might appear in an article. This must include a table and narrative statement that reports and interprets the results of the analysis.

Note: The table must be created using your word processing program. Tables that are copied and pasted from SPSS are not acceptable.

In preparation for a proposed bond sale, the city manager of the City of Appleton requested that you prepare a statement of legal debt margin and a schedule of direct and overlapping debt for the city as of the December 31 year end. You ascertain that the following bond issues are outstanding on that date:

You obtain other information that includes the following items:

1. Assessed valuation of real and taxable personal property in the city totaled $190,000,000.
2. The rate of debt limitation applicable to the City of Appleton was 4 percent of total real and taxable personal property valuation.
3. Electric utility, water utility, and transit authority bonds were all serviced by enterprise revenues. By law, such self-supporting debt is not subject to debt limitation.
4. The convention center bonds and tax increment bonds are subject to debt limitation.
5. The amount of assets segregated for debt retirement at December 31 is $2,000,000.
6. The city’s residents are also taxed by Clyde County for 25 percent of school district and health services debt. The school district has $18,000,000 in outstanding bonds, while health services has $5,000,000 in debt. Finally, one-third of the $1,200,000 of regional library outstanding debt is paid by taxes assessed on Appleton residents.

Prepare a statement of legal debt margin for the city as of December 31 year end.

Taxi Dancing around the Question of Regulation

Uber is a ridesharing service introduced in San Francisco in 2009 and quickly expanded to 140 U.S. cities and 40 foreign countries. Customers “e-hail” a ride through an app on their smartphone and a ride is there within minutes. The service is cheaper than a typical taxi and there is no cash involved as the charges come straight from the customer’s credit card. The service has its detractors, including cab services and some dissatisfied customers.

Management Update: Add drivers to the list of possible Uber detractors. In September 2015, a California judge granted class-action status to an employee status lawsuit filed against the company. The suit is open to all Uber drivers in California. The lawsuit claims Uber misclassified its employees as contract workers. It alleges Uber treats drivers like employees without providing the requisite benefits. Uber plans to appeal the decision saying there really is no “typical” driver, the key question at issue. If the suit is successful, it could mean the end of Uber

“Innovation and regulation simply don’t work together.” So says Larry Downes, the victim of the cab ride described at the outset of the case and formerly of the Northwestern University School of Law and the University of California-Berkeley’s Haas School of Business. Assuming that he’s right, why is this so? Why is regulation often incompatible with innovation? Why do we regulate most industries in the first place? In your opinion, what sort of tradeoffs should we seek when we try to balance the opposing advantages of regulation and innovation?

Charlie is an 8-year-old boy who is having difficulty making friends and sitting still in class. When he goes to school, his teacher complains that he can't sit still. He will sit for 3 minutes but soon after he starts bouncing his leg, and then he begins tapping his pencil. Shortly thereafter, he starts rapping lyrics under his breath. He is performing well in school, but his behavior is distracting others.

Charlie isn't hyperactive like this at home, but his mother is concerned. His mother wants you to prescribe him Xanax for anxiety and Adderall for ADHD. After you do an extensive interview with Charlie, you realize that he is just bored in his U.S History class and would rather be playing basketball in P.E.

However, Charlie's mother insists that you write a few prescriptions. Research suggests that medical professionals (Doctors, Nurse Practitioners, Physician Assistant's, etc.) are often pressured to write prescriptions even when they don't believe that it is the best thing to do for the patient.

Your investigation has led you to believe that Charlie just needs more physical exercise. But his mother continues to insist that Charlie needs medication. How would you explain to his mother what you plan to do?

Use your investigation skills and present your facts to her. Be sure to incorporate at least 1 developmental theory covered in this week's readings to support your argument.
