4

**Step-by-step explanation:**

The question is asking how many cookies can the teacher evenly divide to each student. This can be solved simply by doing a division problem. 18/4 = 4 and a remainder of 2. The question doesn't specify if there can be a remainder or not but each student would get 4 whole cookies and half of a cookie.

As measured by the MAD, the variability ratio is

(MAD of 6th grade heights)/(MAD of 7th grade heights) = 1.2/0.6 = 2.0

The 4th selection is appropriate:

2.0

17^2 = 289

18^2 = 324

Any of the numbers between 289 and 324 exclusive will have a root between 17 and 18

Eg sr(300) = 17.3205... is between 17 and 18 on the number line.
