First you find the median, the middle term (if there are an even number of terms it is the average of the middle two terms.) Since you have 21 terms, odd, you just use the middle term, in this case 8. The first quartile works the same way, but just on the left half between the start and the median...so the first quartile is 6.

The area of 1 tile is 3 1/8 (3.125) x 2 3/4 (2.75) = 8.59375
8.59375 x 9 = 77.34375 inches squared.
Hope this helps! :-) :-P
The formula for this type of question is z=x-u/y
z=-2 (z-value)
u = 27 (mean)
y = 4 (standard deviation)
Therefore -2=x-27/4
You now figure this out like a normal equation
4x-2=4 X x-27/4
-8+27= x-27+27
19=x
Therefore the data value of x is 19
