$$\text { TABLE 2-13 }$$ Given Below Is the Stem-And-Leaf Display Representing the Amount of Display

question 93

Short Answer

$$\text { TABLE 2-13 }$$
Given below is the stem-and-leaf display representing the amount of detergent used in gallons (with leaves in 10ths of gallons) in a month by 25 drive-through car wash operations in Phoenix.
$\begin{array}{l}\begin{array} { l l } \hline\text { Stem}&\text { Leaves }\\\hline9 & 147 \\10 & 02238 \\11 & 135566777 \\12 & 223489 \\13 & 02 \\\hline\end{array}\end{array}$
-Referring to Table 2-13, if a relative frequency or percentage distribution for the detergent data is constructed, using "9.0 but less than 10.0 gallons" as the first class, what percentage of drive-through car wash operations use at least 10 gallons of detergent in a month?
