Swan is a 14-year-old student at the Sea-Cow School for the Performing Arts. Her goal in life is to be a world-acclaimed ballet dancer. She has been dancing ever since she was 4 years old, when her parents enrolled her in a Ballet for Tots program. Swan’s parents have always encouraged her to pursue her dream of dancing professionally. As a young girl, Swan had the perfect body for a ballet dancer, slim and flexible. Within the last year, Swan has become concerned that she is gaining weight. She heard from friends that smoking cigarettes could help her stay thin, although she didn’t exactly know why. Swan became desperate to control her weight and started borrowing cigarettes from friends. Eventually, she was smoking almost a pack of cigarettes a day and felt edgy and irritable if she went without smoking for more than a few hours. She thought about trying diet pills or even barbiturates to avoid the smell of the cigarette smoke.

Swan’s parents have approached you, the school counselor, because they found rolling papers in her room. Although Swan denies using any other drugs, her parents are convinced that she has been smoking marijuana. How would you approach this case? Do you think Swan is at risk for addiction? What questions would you ask Swan and/or her parents? What recommendations would you make?

Q1. Suppose at random 40% of school children develop nausea and vomiting following holiday parties and that you conduct a study to examine this phenomenon, with a sample size of n=50. What is the probability that 12 or more children become sick?

Answer:

Q2. A research study examined the blood vitamin D levels of the entire US population of landscape gardeners. The population average level of vitamin D in US landscapers was found to be 52.07 ng/mL with a standard deviation of 4.567 ng/mL. Assuming the true distribution of blood vitamin D levels follows a Gaussian distribution, what is the 66-th percentile? Recall that the statistic, "percentile", is defined to be the value below which a given percentage of observations are located within the distribution. In other words, for this question find the vitamin D value for which 66% of the observations within the distribution are located to the left of this value.

he newly formed Buffalo School District engaged in the following transactions and other events during the year:levied and collected property taxes of $110 million. 2. It issued $30 million in long-term bonds to construct a building. It placed the cash received in a special fund set aside to account for the bond proceeds. 3. During the year it constructed the building at a cost of $25 million. It expects to spend the $5 million balance in the following year. The building has an estimated useful life of 25 years. 4. It incurred $70 million in general operating costs, of which it paid $63 million. It expects to pay the balance early the following year. 5. It transferred$12million from its general fund to a fund established to account for resources set aside to service the debt. Of this, $10 million was for repayment of the debt; $2 million was for interest. 6. From the special fund established to service the debt, it paid $2 million in interest and $6 million in principal. 7. It collected $4 million in hotel taxes restricted to promoting tourism.Since the resources were restricted they were accounted for in a special restricted fund. During the year, the district spent $3 million on promoting tourism. 8. The district established a supplies store to provide supplies to the district’s various departments by transferring $4 million from the general fund. It accounted for the store in an internal service (proprietary) fund. During the year the store purchased (and paid for) $2 million in supplies. Of these it ‘‘sold’’ $1 million, at cost (for cash),to departments accounted for in the general fund. During the year these departments used all of the supplies that they had purchased. a. Prepare journal entries to record the transactions and other events in appropriate funds. APrepare journal entries to record the transactions and other events in appropriate funds. Assume that governmental funds are accounted for on a modified accrual basis and focus only on current financial resources (and thus do not give balance sheet recognition either to capital assets or long-term debts). Proprietary funds are accounted for on a full accrual basis. b. Prepare a combined balance sheet—one that has a separate column for each of the governmental funds you established. c. Prepare a combined statement of revenues, expenditures, and changes in fund balances for all governmental funds. Prepare a separate statement of revenues, expenses, and changes in fund net position for any proprietary funds you established. d. Prepare a government-wide statement of net position and a government-wide statement of activities in which all funds are consolidated and are accounted for on a full accrual basis. Be sure to include both long-term assets and liabilities on the statement of net position and to depreciate the long-term assets. Also, be sure to adjust for any interfund activity.

Professor Jennings claims that only 35% of the students at Flora College work while attending school. Dean Renata thinks that the professor has underestimated the number of students with part-time or full-time jobs. A random sample of 80 students shows that 38 have jobs. Do the data indicate that more than 35% of the students have jobs? Use a 5% level of significance.

What are we testing in this problem?

(d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level α?

At the α = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant.At the α = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant.    At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant.At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.

(e) Interpret your conclusion in the context of the application.

There is sufficient evidence at the 0.05 level to conclude that more than 35% of the students have jobs.There is insufficient evidence at the 0.05 level to conclude that more than 35% of the students have jobs.

Maya is a senior in high school. She earns $8 an hour working approximately 25 hours a week at the local grocery store. An estimated 30 percent of her pay is deducted for taxes. Maya also earns approximately $15 each month in interest on savings.

Maya still owes money on her used car ($235 a month), but she doesn’t pay rent because she lives with her parents. She is responsible for the following expenses every month: cell phone ($35–$45), gas ($40–$60), and auto insurance ($50). Maya likes to play video games and listen to music, so she frequently buys games and music. Maya typically buys her own clothes and electronic gadgets, but she also receives gifts from her family for special occasions.

One of Maya’s short-term goals is to take a trip to visit her grandparents right after graduation. She expects this to cost $1,000, and she has already saved $500. A long-term goal is to attend college over the next four to five years at the local state school. She plans to pay part of the tuition with scholarship money and from her savings. So far she has set aside $7,000 for her college fund.

Directions:

Create a monthly spending plan for Maya using the information provided. Use this what you have learned to build the plan.

Step 1: List Maya’s anticipated monthly income sources and amounts. Calculate the total income she expects to receive in a month.

Step 2: Add expense categories and insert predicted amounts for each category. Remember to include “pay yourself first” or savings amounts to build up Maya’s trip fund and college fund. Calculate the predicted total amount needed to cover expenses and savings goals.

Step 3: Compare the total income to total expenses. Make adjustments to the expense amounts to ensure that Maya can cover the expenses with the income she expects each month.

You can use word, excel or your other application to present your work.

Reba Dixon is a fifth-grade school teacher who earned a salary of $38,300 in 2018. She is 45 years old and has been divorced for four years. She receives $1,260 of alimony payments each month from her former husband (divorced in 2016). Reba also rents out a small apartment building. This year Reba received $50,000 of rental payments from tenants and she incurred $19,500 of expenses associated with the rental.

Reba and her daughter Heather (20 years old at the end of the year) moved to Georgia in January of this year. Reba provides more than one-half of Heather’s support. They had been living in Colorado for the past 15 years, but ever since her divorce, Reba has been wanting to move back to Georgia to be closer to her family. Luckily, last December, a teaching position opened up and Reba and Heather decided to make the move. Reba paid a moving company $2,130 to move their personal belongings, and she and Heather spent two days driving the 1,450 miles to Georgia.

Reba rented a home in Georgia. Heather decided to continue living at home with her mom, but she started attending school full-time in January at a nearby university. She was awarded a $3,120 partial tuition scholarship this year, and Reba helped out by paying the remaining $500 tuition cost. If possible, Reba thought it would be best to claim the education credit for these expenses. Reba wasn't sure if she would have enough items to help her benefit from itemizing on her tax return. However, she kept track of several expenses this year that she thought might qualify if she was able to itemize. Reba paid $5,920 in state income taxes and $12,620 in charitable contributions during the year. She also paid the following medical-related expenses for herself and Heather:

Insurance premiums $ 5,915

Medical care expenses $ 1,220

Prescription medicine $ 470

Nonprescription medicine $ 220

New contact lenses for Heather $ 320

Shortly after the move, Reba got distracted while driving and she ran into a street sign. The accident caused $1,020 in damage to the car and gave her whiplash. Because the repairs were less than her insurance deductible, she paid the entire cost of the repairs. Reba wasn’t able to work for two months after the accident. Fortunately, she received $2,120 from her disability insurance. Her employer, the Central Georgia School District, paid 60% of the premiums on the policy as a nontaxable fringe benefit and Reba paid the remaining 40% portion.

A few years ago, Reba acquired several investments with her portion of the divorce settlement. This year she reported the following income from her investments: $2,320 of interest income from corporate bonds and $1,620 interest income from the City of Denver municipal bonds. Overall, Reba’s stock portfolio appreciated by $12,120 but she did not sell any of her stocks.

Heather reported $6,440 of interest income from corporate bonds she received as gifts from her father over the last several years. This was Heather’s only source of income for the year.

Reba had $10,000 of federal income taxes withheld by her employer. Heather made $1,000 of estimated tax payments during the year. Reba did not make any estimated payments. Reba had qualifying insurance for purposes of the Affordable Care Act (ACA).

a. Determine Reba’s federal income taxes due or taxes payable for the current year.

My calculations:

Gross income: 38,300+15,120+50,000+1,272+2,320 = 107,012 - Rental expense:19,500 = 87,512 AGI

Itemized deduction: medical 0 + state 5920 + charitable 12620 = 18,540> Standard deduction: HOH 18,000

Taxable income: 68,972 (87,512 - 18,540)

Tax on taxable income: 9,722 ([68,972-51,800 x 22%] +5,944)

Credits: 6,600 (AOC: 500 + QBI: 6100)

Tax prepayments: 10,000

Tax Refund: 6,878

**Not sure I have medical expenses and credits correct **

Medical expenses total: $4276? (Gross Income 87,512 X 7.5% = 6563) so zero is deductible? ([5915 x 40%]+1120+470+320)=4276

Credits: AOC credit of $500, should it include QBI? QBI credit would be $6,100? (30,500 x 20%=6,100) so can take the full QBI because [(AGI: 87,512 - itemized ded: 18,540 = 68,972, taxable income) x 20%=13,758]
