Instruction 2-14
The ordered array below resulted from taking a sample of 25 batches of 500 computer chips and determining how many in each batch were defective.
Defects
$\begin{array} { l r r r r r r r r r r r } 1 & 2 & 4 & 4 & 5 & 5 & 6 & 7 & 9 & 9 & 12 & 12 &15\ 17 & 20 & 21 & 23 & 23 & 25 & 26 & 27 & 27 & 28 & 29 & 29 \end{array}$
-Referring to Instruction 2-14,if a frequency distribution for the defects data is constructed,using "0 but less than 5" as the first class,the relative frequency of the "15 but less than 20" class would be ________.
