What can you conclude from this streak plate? Select one: a. The plate is contaminated because only one type of bacteria should grow b. It was made from a pure culture of bacteria c.

The following table shows ceremonial ranking and type of pottery sherd for a random sample of 434 sherds at a location in the Sand Canyon Archaeological Project, Colorado (The Architecture of Social Integration in Prehistoric Pueblos, edited by Lipe and Hegmon). $$\begin{array}{lcccc} \hline \begin{array}{l} \text { Ceremonial } \\ \text { Ranking } \end{array} & \begin{array}{c} \text { Cooking Jar } \\ \text { Sherds } \end{array} & \begin{array}{c} \text { Decorated Jar Sherds } \\ \text { (Noncooking) } \end{array} & \text { Row Total } \\ \hline \mathrm{A} & 86 & 49 & 135 \\ \hline \mathrm{B} & 92 & 53 & 145 \\ \hline \mathrm{C} & 79 & 75 & 154 \\ \hline \text { Column Total } & 257 & 177 & 434 \\ \hline \end{array}$$ Use a chi-square test to determine if ceremonial ranking and pottery type are independent at the 0.05 level of significance.
