Cincinnati, Ohio, also known as the Queen City, has a population of approximately 298,000 and is the third largest city in the state of Ohio. The Cincinnati metropolitan area has a population of about 2.2 million. The city is governed by a mayor and a nine-member city council. The city manager, who is responsible for the day-to-day operation of the city, reports to the mayor and city council. The city manager recently created the Office of Performance and Data Analytics with the goal of improving the efficiency of city operations. One of the first tasks of this new office is to review the previous year’s expenditures. The file QueenCity contains data on the previous year’s expenditures, including the following:
Department: The number of the department incurring the expenditure
Department Description: The name of the department incurring the description
Category: The category of the expenditure
Fund: The fund to which the expenditure was charged
Expenditure: The dollar amount of the expense
Table 2.21 shows the first four entries of the 5427 expenditures for the year. The city manager would like to use this data to better understand how the city’s budget is being spent.

Answer to Problem 3CP
The following table represents the total amount of expenditure by category and percentage of total expenditures by category:
Category | Total expenditure | Percentage of total expenditure |
Capital | $198,365,854 | 29.98% |
Payroll | $145,017,555 | 21.92% |
Debt service | $86,913,978 | 13.14% |
Contractual services | $85,043,249 | 12.85% |
Fringe benefits | $66,053,340 | 9.98% |
Fixed costs | $53,732,177 | 8.12% |
Materials and supplies | $19,934,710 | 3.01% |
Inventory | $6,393,394 | 0.97% |
Payables | $180,435 | 0.03% |
Grand Total | $661,634,693 | 100.0% |
The bar chart for “Category” is given below:
Explanation of Solution
Calculation:
The table represents the sample of 5,427 entries and the annual expenditures for queen city (City C and City O) for the year. The five types of variables present in the data are department serial number, department description, category name, fund, and expenditure.
From the data set, the variable “Category” consists of nine entities, namely capital, payroll, debt service, contractual services, fringe benefits, fixed costs, materials and supplies, inventory, and payable.
Therefore, the following table shows the amount of all nine entities’ total expenditure by category:
Category | Total expenditure |
Capital | $198,365,854 |
Payroll | $145,017,555 |
Debt service | $86,913,978 |
Contractual services | $85,043,249 |
Fringe benefits | $66,053,340 |
Fixed costs | $53,732,177 |
Materials and supplies | $19,934,710 |
Inventory | $6,393,394 |
Payables | $180,435 |
Grand Total | $661,634,693 |
The percentage for capital is calculated as the ratio of total expenditure for capital to the grand totals of all categories.
The following table shows the percentage of amount of all nine entities’ total expenditure by category:
Category | Total expenditure | Percentage of total expenditure |
Capital | $198,365,854 | 29.98% |
Payroll | $145,017,555 | 21.92% |
Debt service | $86,913,978 | 13.14% |
Contractual services | $85,043,249 | 12.85% |
Fringe benefits | $66,053,340 | 9.98% |
Fixed costs | $53,732,177 | 8.12% |
Materials and supplies | $19,934,710 | 3.01% |
Inventory | $6,393,394 | 0.97% |
Payables | $180,435 | 0.03% |
Grand Total | $661,634,693 | 100.0% |
Software procedure:
Step-by-step software procedure to obtain the bar chart for category using EXCEL software:
- In Excel sheet, enter Category in one column and Percentage of total Expenditure in another column.
- Select the data, and then choose Insert > Insert Column Bar Charts.
- Select Clustered Column under More Column Charts.
Output using the EXCEL software is given below:
From the obtained table and bar chart, it can be observed that the sum of capital expenditures and payroll contributes 50% of all expenditures.
Also, the total expenditures are over $660 million. Debt service seems to be high, and it is found to be over 10% of total expenditures.

Total | 661,634,693 |
The percentage for fund is calculated as the ratio of total expenditure to the grand totals all funds.
Therefore, the following table shows the percentage of amount of all funds’ total expenditure by funds:
Fund | Percentage of total expenditure |
050 - general fund | 25.5% |
980 - capital projects | 16.0% |
701 - metropolitan sewer district of greater Cincinnati | 12.7% |
704 - metropolitan sewer district capital improvements | 8.8% |

302 - income tax - infrastructure | 1.1% |
other (less than 1% each) | 12.9% |
Total | 100.0% |
Software procedure:
Step-by-step software procedure to obtain bar chart for fund using Excel:
- In Excel sheet, enter Fund in one column and Percentage of total Expenditure in another column.
- Select the data, and then choose Insert > Insert Column Bar Charts.
- Select Clustered Column under More Column Charts.
Output using Excel is given below:
Interpretation:
- From the obtained table and bar chart, it can be observed that the fund category 050-General fund seems to be high, in terms of total expenditure percentage.

- +900 pts /1100 Due: Tue Submit Answer Many young men in North America and Europe (but not in Asia) tend to think they need more muscle to be attractive. One study presented 200 young American men with 100 images of men with various levels of muscle. Researchers measure level of muscle in kilograms per square meter (kg/m²) of fat-free body mass. Typical young men have about 20 kg/m². Each subject chose two images, one that represented his own level of body muscle and one that he thought represented "what women prefer." The mean gap between self-image and "what women prefer" was 2.35 kg/m². Suppose that the "muscle gap" in the population of all young men has a Normal distribution with standard deviation 2.5 kg/m² Give a 90% confidence interval for the mean amount of muscle think they should add to be attractive to women (Enter your answers rounded to four decimal places.) young 00 ible lower limit = 00 upper limit = 00 00 100 100 3 # E 80 DOD F4 $ 94 55 6 MacBook Air R T Y kg/m² kg/m²…arrow_forwardIs the normal distribution important in statistics analysis?
