Final answer:
Due to the lack of specific data or a formula, it's impossible to determine the percentage of FTEs from 528.5 to 1,447.5. To find the answer, one must refer to the relevant dataset or formula that pertains to FTE numbers.
Step-by-step explanation:
The question is asking for a specific percentage of Full-Time Equivalent Students (FTEs) within a given range. However, the information provided does not allow for determining the exact percentage within the range of 528.5 to 1,447.5 directly. FTE is a standard measure of an employee's productivity that converts part-time employees' hours into the equivalent number of full-time hours. The solution likely involves analyzing a dataset or using a given formula, but the actual data or formula necessary to answer this question isn't provided in the information above.
Without additional context or a dataset relating to FTE numbers, it's not possible to accurately calculate the percentage of FTEs that fall within that specific range. If the problem originates from a statistics course, it may involve concepts such as Standard Deviation, IQR (Interquartile Range), or Percentiles. You will need to refer to your course material or the specific data set from which the question is derived to find the answer.
