35. Researchers surveyed 100 patients on their preferred procedure. Their preferences include the following: 35 patients preferred infusions, 30 preferred incision/drainage, 25 preferred wound care, and 10 preferred vital signs. What is the relative frequency for patients choosing wound care as their preferred procedure?
Answer: B
The relative frequency for patients choosing wound care as their preferred procedure is 0.25.
To calculate the relative frequency of patients choosing wound care, divide the number of patients who preferred wound care (25) by the total number of patients surveyed (100). This results in a relative frequency of 0.25.
A) 0.1
Option A is incorrect because a relative frequency of 0.1 would imply that only 10 patients preferred wound care, which does not match the survey data indicating that 25 patients preferred this option.
B) 0.25
Option B is correct as it accurately represents the relative frequency of patients who preferred wound care. The calculation (25 patients preferring wound care divided by 100 total patients) gives a relative frequency of 0.25.
C) 0.3
Option C is incorrect because a relative frequency of 0.3 would suggest that 30 patients preferred wound care. However, the data shows that only 25 patients indicated this preference.
D) 0.35
Option D is also incorrect since it implies that 35 patients preferred wound care, which is inaccurate according to the survey results that state only 25 patients chose wound care as their preferred procedure.
Conclusion
The correct relative frequency of 0.25 for patients selecting wound care is derived from the accurate calculation based on the provided data. Options A, C, and D do not align with the number of patients surveyed, making them invalid choices. Therefore, Option B is definitively the correct answer.
