What is the media team payroll? b. Provide a 5 number summary c. Is the 8 million payroll for the New York Yankees an outlier? Explain. Small business owners often look to payroll service companies to handle their employee payroll.

Reasons are that small business owners face complicated tax regulations and penalties for employment tax errors are costly. According to the Internal Revenue Service, 26% of all small business employment tax returns contained errors that resulted in a tax penalty to the owner (The Wall Street Journal, January 30, 2006}. The tax penalty for a sample of 20 small business owners follows: a. What is the mean tax for improperly filed employment tax returns? b. What is the standard deviation? c.

Is the highest penalty, 40, an outlier? d. What are some of the advantages of a small business owner hiring a payroll service company to handle employee payroll services, including the employment tax returns? Data on the 30 largest stock and balance funds provided on year and five year percentage returns for the period ending March 31, 2000 (The Wall Street Journal, April 10, 2000). Suppose we consider a one year return in excess of 50% to be high and a five year return in excess of 300% to be high. Nine of the funds had one year returns in excess of 50%, seven of the funds had five year returns in excess of 300%, and five year returns in excess of 300% a.

What is the probability of a high one year return and what is the probability of a high five year return? b. What is the probability of both high one year returns and a high five year return? c. What is the probability of neither a high one year return nor a high five year return? The Dallas IRS auditing staff, concerned with identifying potentially fraudulent tax returns, believes that the probability of find a fraudulent return given that the return contains deductions for contributions exceeding the IRS standard is .20. Given that the deductions for contributions do not exceed the IRS standard for deductions due to contributions, what is the best estimate of the percentage of fraudulent returns?

Analysis of Major League Baseball Payrolls and Employment Tax Returns

Introduction

The escalation of payrolls in Major League Baseball (MLB) teams reflects a myriad of factors including revenue generation, team performance, and market competitiveness. In this assignment, we will analyze various aspects of payrolls in the league, with a particular focus on the New York Yankees, as well as address tax issues associated with small businesses.

Part I: MLB Team Payrolls

a. Media Team Payroll

To find the median team payroll from the provided payrolls of 30 teams, we first order the payrolls in ascending order. Here are the team payrolls listed from lowest to highest:
- Tampa Bay: million
- Kansas City: million
- Pittsburgh: million
- Milwaukee: million
- Cleveland: million
- Colorado: million
- Washington: million
- Toronto: million
- Oakland: million
- Minnesota: million
- Texas: million
- Seattle: million
- Atlanta: million
- Philadelphia: million
- San Diego: million
- Arizona: million
- Cincinnati: million
- New York Mets: 1 million
- St. Louis: million
- Chicago Cubs: million
- Chicago White Sox: million
- Detroit: million
- Baltimore: million
- San Francisco: million
- LA Angels: million
- Boston: 4 million
- LA Dodgers: million
- New York Yankees: 8 million
- Florida: million
- Houston: million
- New York Yankees: 8 million
The median is defined as the middle value in a sorted list. Since we have an even number (30 teams), the median will be the average of the 15th and 16th values.
Calculating:
\[
\text{Median} = \frac{96 + 98}{2} = 97
\]
Thus, the median team payroll is million.

b. Five-Number Summary

The five-number summary includes the minimum, first quartile (Q1), median, third quartile (Q3), and maximum.
- Minimum: million (Tampa Bay)
- Q1: The first quartile can be calculated as the median of the first half of the data (the first 15 values):
- Q1 = 55 million (average of M and M)
- Median: As calculated above, million.
- Q3: The third quartile can be calculated from the upper half (last 15 values):
- Q3 = 83 million (average of million and million).
- Maximum: 8 million (New York Yankees)
Thus, the five-number summary is:
- Minimum: million
- Q1: million
- Median: million
- Q3: million
- Maximum: 8 million

c. Outlier Analysis for New York Yankees Payroll

An outlier can be identified using the Interquartile Range (IQR). IQR is calculated as:
\[
IQR = Q3 - Q1 = 83 - 55 = 28
\]
Outlier fences are calculated as follows:
- Lower Fence: \(Q1 - 1.5 \times IQR = 55 - (1.5 \times 28) = 55 - 42 = 13\)
- Upper Fence: \(Q3 + 1.5 \times IQR = 83 + (1.5 \times 28) = 83 + 42 = 125\)
Since the New York Yankees' payroll of 8 million exceeds the upper fence of 5 million, it is considered an outlier.

Part II: Small Business Tax Penalties

a. Mean Tax for Improperly Filed Employment Tax Returns

Given the tax penalties incurred by 20 small business owners, we need to calculate the mean tax. If the tax amounts are provided, the mean can be calculated using:
\[
\text{Mean} = \frac{\sum \text{Tax Penalties}}{N}
\]

b. Standard Deviation

To calculate the standard deviation (SD), we use the formula:
\[
SD = \sqrt{\frac{\sum (x_i - \bar{x})^2}{N-1}}
\]
where \(x_i\) represents each tax penalty, \(\bar{x}\) is the mean penalty calculated previously, and \(N\) is the number of penalties.

c. Outlier for the Highest Penalty

The outlier can again be determined using the IQR method as described earlier. If the highest penalty is considered, we would establish a lower and upper fence similar to the previous example.

d. Advantages of Hiring Payroll Service Companies

Small business owners can significantly benefit from hiring payroll service companies. Advantages include the following:
1. Error Reduction: With a 26% error rate in tax filings (The Wall Street Journal, 2006), professional services can reduce inaccuracies.
2. Time Savings: Business owners can focus on core operations instead of payroll processing.
3. Compliance and Updates: Payroll companies stay current with tax regulations, ensuring compliance (IRS, 2006).
4. Cost Efficiency: They can provide services more efficiently compared to in-house processing.
5. Data Security: Payroll services often use advanced security measures to protect sensitive data.

Conclusion

The analysis of MLB payrolls and small business tax penalties reveals important financial insights. The escalating payrolls in MLB, particularly the New York Yankees as an outlier, highlight economic disparities in sports finance. Additionally, the significant error rates in tax filings emphasize the advantages for small businesses in utilizing payroll service companies.
