After reviewing past history, you have assembled the following table showing the frequency of certain levels of sales over the past 40 months. If the largest random number used to represent sales of 300 units is 1.00, what will be the smallest number used to represent sales of 300 units?
$$\begin{array} { | c | r | l | }
\hline \text { Sales (units) } & \text { Frequency } & \text { Corregonding Randam Numbers } \
\hline 100 & 12 & \
\hline 150 & 6 & \
\hline 200 & 8 & \
\hline 250 & 4 & \
\hline 300 & 10 & ? ? \leq x \leq 1\
\hline
\end{array}$$
A) 0.1000
B) 0.3000
C) 0.5000
D) 0.6500

The cumulative frequency for sales of 300 units is 40 (12+6+8+4+10). The cumulative frequency for sales less than 300 units is 30 (12+6+8+4). Therefore, the smallest random number for 300 units is 30/40 = 0.7500.
