Reba Dixon is a fifth-grade school teacher who earned a salary of $38,000 in 2015. She is 45 years old and has been divorced for four years. She received $1,200 of alimony payments each month from her former husband. Reba also rents out a small apartment building. This year Reba received $30,000 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 $2,010 to move their personal belongings, and she and Heather spent two days driving the 1,426 miles to Georgia. During the trip, Reba paid $143 for lodging and $85 for meals. Reba’s mother was so excited to have her daughter and granddaughter move back to Georgia that she gave Reba $3,000 to help out with the moving costs. |
|
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 $3,000 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 $2,800 in state income taxes and $6,500 in charitable contributions during the year. She also paid the following medical-related expenses for her and Heather: |
| Insurance premiums | $ | 4,795 |
| Medical care expenses | 1,100 | |
| Prescription medicine | 350 | |
| Nonprescription medicine | 100 | |
| New contact lenses for Heather | 200 | |
|
Shortly after the move, Reba got distracted while driving and she ran into a street sign. The accident caused $900 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 $2,000 from her disability insurance. Her employer, the Central Georgia School District, paid 60 percent of the premiums on the policy as a nontaxable fringe benefit and Reba paid the remaining 40 percent 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: $2,200 of interest income from corporate bonds and $1,500 interest income from City of Denver municipal bonds. Overall, Reba’s stock portfolio appreciated by $12,000 but she did not sell any of her stocks. |
|
Heather reported $3,200 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 $500 of estimated tax payments during the year. Reba did not make any estimated payments. |
| a. Determine Reba’s federal income tax refund or taxes payable for the current year. Use Tax Rate Schedule for reference. (Round percentages to two decimal places. Round your intermediate computations and final answers to the nearest whole dollar amount. Leave no answer blank. Enter zero if applicable.) |

Suppose that a safety group surveyed
1,300
drivers. Among those surveyed,
67%
said that careless or aggressive driving was the biggest threat on the road, and
37
said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a
99%
confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users.
The confidence interval estimate is (Round to three decimal places as needed. Use ascending order.)
Interpret the confidence interval estimate.
A.There is a
0.99
probability that the sample proportion of drivers who are annoyed by cell phone users is in the interval.
B.There is
99%
confidence that the population proportion of drivers who are annoyed by cell phone users is in the interval.
C.There is a
0.99
probability that the population proportion of drivers who are annoyed by cell phone users is in the interval.
D.There is
99%
confidence that the population proportion of drivers who are annoyed by cell phone users is equal to one of the bounds of the interval
A pharmaceutical company operates retail pharmacies in 10 eastern states. Recently, the company's internal audit department selected a random sample of
300 prescriptions issued throughout the system. The objective of the sampling was to estimate the average dollar value of all prescriptions issued by the company. The data collected were
x overbarxequals=$14.45 and sequals=5.00 Complete parts a and b below.
a. Determine the 90% confidence interval estimate for the true average sales value for prescriptions issued by the company. Interpret the interval estimate.
The 90% confidence interval is (Round to the nearest cent as needed. Use ascending order.)
Interpret the interval. Choose the correct answer below.
A.
The company believes that the true mean prescription amount falls between these two values 90% of the time.
B.
There is a 0.90 probability that the true mean prescription amount is between these two values.
C.
The company believes with 90% confidence that the true mean prescription amount is between these two amounts.
D.
The company believes with 90% confidence that the sample mean prescription amount is between these two amounts.
b. One of its retail outlets recently reported that it had monthly revenue of
$7 485 from 531
prescriptions. Are such results to be expected? Should that retail outlet be audited?Assuming the population mean is at the upper limit of the 90% confidence interval computed in part a, the upper limit of the 90% confidence interval for the expected total monthly revenue for
531
prescriptions would be
$nothing.
Assuming the population mean is at the lower limit of the 90% confidence interval computed in part a, the lower limit of the 90% confidence interval for the expected total monthly revenue for
531
prescriptions would be
Given that this outlet reported sales of
$7, 485 from 531
prescriptions, there is good or no
reason to believe that this is out of line. The retail outlet
should not or should be audited.

A typical college student spends an average of 2.55 hours a day using a computer. A sample of 13 students at The University of Findlay revealed the sample mean of 2.70 hours and sample standard deviation of 0.51 hours.
Can we conclude that the mean number of hours per day using the computer by students at The University of Findlay is the same as the typical student’s usage? Use the five step hypothesis testing procedure and the 0.05 significance level.

A university wants to start a hockey team finding that 83% of a random sample of 100 people support the establishment of said team. However, the sample appears to contain 80 mean and 20 women; another random sample of the university body suggests that the true percentage of support for a hockey team is 55%. Calculate the test statistic one would use to determine if there is a significant difference between the male dominated sample and the "normal" sample.

Could you show me how you completed this?
A state board of directors is trying to determine if there is a difference in pay for teachers at its two universities. The first university has 42 teachers with an average pay of $58,500 and a population standard deviation of $3,200. The second university has 51 teachers with an average pay of $60,200 and a population standard deviation of $11,700. Determine if there is a difference using a 0.05 level of significance.
Thank you!
