Experiment 3
Part 1:
Dr. Schwartz wanted to examine the hypothesis that smelling peppermint affects exercise intensity, so she used random assignment in her first experiment on this topic. The peppermint group exercised in a room in which a peppermint scent was released once each minute, while the no peppermint group exercised in an unscented room. She measured the distance participants cycled in 20 minutes on indoor bicycles. After she completed that first experiment, Dr. Schwartz realized that perhaps her results in the first experiment could be attributable to the failure of random assignment to balance the weight of participants in the two groups. Thinking that this alternative explanation might explain why she got nonsignificant results in the first experiment, she decided to match participants on weight. She randomly assigned the two heaviest participants to either the peppermint or no peppermint conditions by flipping a coin, and then randomly assigned the next two heaviest participants, and so on.
Using the data shown below, conduct the appropriate statistical test in SPSS to determine whether there is a statistically significant difference between how far the participants in the peppermint condition rode vs. how far participants in the no peppermint condition rode.
Peppermint | No Peppermint | |
Pair 1 | 2.3 | 2.0 |
Pair 2 | 2.7 | 3.1 |
Pair 3 | 3.4 | 3.5 |

Part 2:
Next, Dr. Schwartz wanted to see what would happen if she had each participant cycle once in the peppermint condition and once in the no-peppermint condition. Participants were counterbalanced, with half of them cycling on Day 1 in the peppermint condition, and the other half cycling on Day 1 in the no peppermint condition. On Day 2, one week later, the participants cycled in the condition they had not yet completed.
Using the data shown below, conduct the appropriate statistical test in SPSS to determine whether there is a statistically significant difference between how far the participants rode in 20 minutes when in the peppermint condition vs. when they were in the no peppermint condition.
Peppermint | No Peppermint | |
Participant 1 | 2.5 | 2.0 |

The Byrds provide over half of the support of their two children, Cynthia (born January 25, 1992, Social Security number 123-45-6788) and John (born February 7, 1996, Social Security number 123-45-6786). Both children are full-time students and live with the Byrds except when they are away at college. Cynthia earned $4,200 from a summer internship in 2016, and John earned $3,800 from a part-time job.
During 2016, the Byrds provided 60% of the total support of Bruce's widower father, Sam Byrd (born March 6, 1940, Social Security number 123-45-6787). Sam lived alone and covered the rest of his support with his Social Security benefits. Sam died in November, and Bruce, the beneficiary of a policy on Sam's life, received life insurance proceeds of $1,600,000 on December 28.
The Byrds had the following expenses relating to their personal residence during 2016:
| Real estate property taxes | $5,000 |
| Qualified interest on home mortgage | 8,700 |
| Repairs to roof | 5,750 |
| Utilities | 4,100 |
| Fire and theft insurance | 1,900 |
The Byrds had the following medical expenses for 2016:
| Medical insurance premiums | $4,500 |
| Doctor bill for Sam incurred in 2015 and not paid until 2016 | 7,600 |
| Operation for Sam | 8,500 |
| Prescription medicines for Sam | 900 |
| Hospital expenses for Sam | 3,500 |
| Reimbursement from insurance company, received in 2016 | 3,600 |
The medical expenses for Sam represent most of the 60% that Bruce contributed toward his father's support.
Other relevant information follows:
When they filed their 2015 state return in 2016, the Byrds paid additional state income tax of $900.
During 2016, Alice and Bruce attended a dinner dance sponsored by the Lowell Police Disability Association (a qualified charitable organization). The Byrds paid $300 for the tickets. The cost of comparable entertainment would normally be $50.
The Byrds contributed $5,000 to Lowell Presbyterian Church and gave used clothing (cost of $1,200 and fair market value of $350) to the Salvation Army. All donations are supported by receipts, and the clothing is in very good condition.
Alice and Bruce made a gift to a needy family who lost their home in a fire ($100). In addition, they made several cash gifts to homeless men downtown ($35).
In 2016, the Byrds received interest income of $2,750, which was reported on a Form 1099–INT from Second National Bank, 125 Oak Street, Lowell, MA 01850 (Employer Identification Number 98-7654322).
The home mortgage interest was reported on Form 1098 by Lowell Commercial Bank, P.O. Box 1000, Lowell, MA 01850 (Employer Identification Number 98- 7654323). The mortgage (outstanding balance of $425,000 as of January 1, 2016) was taken out by the Byrds on May 1, 2012.
Alice's employer requires that all employees wear uniforms to work. During 2016, Alice spent $850 on new uniforms and $566 on laundry charges.
Bruce paid $400 for an annual subscription to the Journal of Franchise Management and $741 for annual membership dues to his professional association.
Neither Alice's nor Bruce's employer reimburses for employee expenses.
The Byrds do not keep the receipts for the sales taxes they paid and had no major purchases subject to sales tax.
All members of the Byrd family had health insurance coverage for all of 2016.
This year the Byrds gave each of their children $2,000, which was then deposited into their Roth IRAs.
Alice and Bruce paid no estimated Federal income tax. Neither Alice nor Bruce wants to designate $3 to the Presidential Election Campaign Fund.
Required:
Compute net tax payable or refund due for Alice and Bruce Byrd for 2016. If they have overpaid, they want the amount to be refunded to them.
Make realistic assumptions about any missing data.
If an amount box does not require an entry or the answer is zero, enter "0".
Enter all amounts as positive numbers.
It may be necessary to complete the tax schedules before completing Form 1040.
When computing the tax liability, do not round your immediate calculations. If required, round your final answers to the nearest dollar.

you are working
as an administrative assistant in a busy GP practice in a suburb
where the community consists of people newly arrived in Australia
and a younger cohort of individuals who have moved to the area and
are heroin addicts. The GP clinic is the only clinic in the area
that provides a bulk billing service and needle exchange
program.
Mrs. Rizzo is an elderly lady of 78 years, from Italy. Mrs. Rizzo was brought to Australia by her son and daughter in law after her husband died. Mrs. Rizzo does not speak any English but relies on her son to interpret for her. Mrs. Rizzo has been in Australia for over 10 years but has made no effort to learn English and except for when her son accompanies her rarely leaves the house.
On arrival at the surgery it was apparent that Mrs. Rizzo was in pain. There was a lot of yelling, gesturing, pulling of hair and crying. Another patient attending the clinic tells her to shut up™ and asks if you could put the old bag outside™. Her son became very upset and soon both the son and the other client were yelling at each other. Mrs. Rizzo continued to wail.
You need to deal with this situation but privately
you felt that Mrs. Rizzo was making a lot of fuss.
