Multiple Choice

A bakery is considering hiring another clerk to better serve customers. To help with this decision, records were kept to determine how many customers arrived in 10-minute intervals. Based on 100 10-minute intervals, the following probability distribution and random number assignments developed.
$$\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Number of } \\\text { Arrivals }\end{array} & \text { Probability } & \begin{array} { c } \text { Random } \\\text { numbers }\end{array} \\\hline 6 & .1 & .01 - .10 \\\hline 7 & .3 & .11 - .40 \\\hline 8 & .3 & .41 - .70 \\\hline 9 & .2 & .71 - .90 \\\hline 10 & .1 & .91 - .00 \\\hline\end{array}$$
-Suppose the next three random numbers were .11, .42 and .84. Use these values to simulate arrivals into the bakery and determine the average number of arrivals per 10-minute period based on these occurrences. The average number of arrivals per 10-minute period is:
