Question

the rotc program has been found on college campuses for over 60 years but in recent years cuts have been made in universities that are not producing the number of commissioned officers the program was designed to produce. statistics showing the number of officers produced in recent years have been reviewed and funding is shifting to those universities that produce the greatest numbers. funds from closing the program in 13 universities will shift to 56 other universities and expand their programs. one goal in shifting the funds is to continue focus on diversity. the past decade has seen a 5% growth in the number of minorities in active duty which now comprises almost 30% of the officers. source: blinder, a.

Explanation:

• Range: It is a measure of dispersion, calculated as the difference between the maximum and minimum values in a data set.
• Mode: It is the value that appears most frequently in a data set.
• Median: It is the middle - value when the data is arranged in ascending or descending order.
• Mean: The formula for the mean \(\bar{x}\) of a data set \(x_1,x_2,\cdots,x_n\) is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_i}{n}\), which is calculated by dividing the sum of the data (\(\sum_{i=1}^{n}x_i\)) by the number of data points (\(n\)).

Answer:

D. Mean
