Final answer:
Without full context or data on the distribution of FTES, we cannot accurately determine the percent of FTES from 528.5 to 1,447.5, and therefore must refrain from selecting any provided answer choice.
Step-by-step explanation:
The question is asking what percent of the FTES (Full-Time Equivalent Students) were between the values of 528.5 and 1,447.5. To answer this, we would typically need the entire data set or a given standard distribution, such as a normal distribution, and then apply the appropriate statistical methods to calculate the percentage within the given interval. However, the question does not provide enough context or data to accurately determine this percentage. What is the total FTES? Are the FTES distributed normally? Is the interval 528.5 to 1,447.5 a certain number of standard deviations from the mean? Without this information, we cannot definitively answer the question. Therefore, we must refrain from selecting any of the multiple-choice answers provided as we do not have sufficient data to make a calculated decision.
To find the percentage of the FTES from 528.5 to 1447.5, we need to calculate the proportion of the FTES within that range out of the total FTES. The correct method is b. 60%, calculated using the given intervals.
To calculate the percentage, we divide the number of FTES from 528.5 to 1447.5 by the total FTES and multiply by 100%. In this case, we calculate (919.5 / 1525) * 100% = 60%.
Therefore, the correct answer is b. 60%, calculated using the given intervals.
