The Correct Answer and Explanation is:
The correct answer is 25%.
To determine the proportion of employees who have a PC, we first need to analyze the data provided in the table. The process involves two main steps: counting the total number of employees and then counting the specific number of employees who use a PC.
First, we identify the total number of employees listed. By counting each entry in the “Employee” column, we can see there are eight individuals: James, Tanya, Mary, Charles, Lilli, Andrew, Tina, and Thomas. This gives us a total of 8 employees in the group.
Next, we examine the “Computer” column to find out how many of these employees use a PC. We must scan the list and count every instance of the entry “PC”. Looking through the column, we find that James is listed with a PC and Lilli is also listed with a PC. The other six employees are listed with a Mac. Therefore, there are 2 employees who have a PC.
With these two numbers, we can calculate the proportion. The formula for the proportion is the number of employees in the specific category (PC users) divided by the total number of employees. In this case, the calculation is 2 divided by 8.
The fraction 2/8 simplifies to 1/4. To express this proportion as a percentage, which is how the answer choices are formatted, we convert the fraction to a decimal and multiply by 100. The fraction 1/4 is equivalent to the decimal 0.25. Multiplying 0.25 by 100 gives us 25.
Thus, 25% of the employees have a PC. This matches the selected option in the quiz, confirming it as the correct choice based on a clear and logical breakdown of the provided data.
