Final answer:
The proportion of nurses with five or more years of experience can be determined by dividing the number of nurses with five or more years of experience by the total number of nurses in the sample.
Step-by-step explanation:
The proportion of nurses with five or more years of experience can be determined by finding the number of nurses in the sample who have five or more years of experience and dividing it by the total number of nurses in the sample.
Let's assume that 30 nurses in the sample have five or more years of experience. Since the sample size is 100, the proportion can be calculated as:
Proportion = 30/100 = 0.3
Therefore, 30% of the nurses in the sample have five or more years of experience.
