Answer

Explanation:

Step1: Recall MAD meaning

MAD measures average distance from mean.

Step2: Calculate deviation of 400

Deviation of 400 from mean 163.75 is (|400 - 163.75|=236.25).

Step3: Analyze impact on variability

Since 236.25 > 65, new data - point increases variability.

Step4: Determine new MAD

Increased variability means new MAD > 65.

Answer:

A MAD of 65 means that the monthly enrollment counts were an average of 65 from the mean. An enrollment of 400 has a deviation value that is greater than the MAD. The data will have greater variability when January's enrollment is included. This will result in a new MAD that is greater than 65.
