A Spinner Is Mounted on a Piece of Cardboard Divided $\frac { 1 } { 6 }$

Short Answer

A spinner is mounted on a piece of cardboard divided into six areas of equal size. Each of the six areas is a different color (blue, yellow, red, green, white and orange). When the spinner is spun, each color should be selected by the spinner approximately $\frac { 1 } { 6 }$ of the time. A student suspects that a certain spinner is defective. The suspected spinner is spun 90 times. The results are shown below. Test the student's claim. Use $\alpha = 0.10$ .
$\begin{array}{l|cccccc}\text { Color } & \text { Blue } & \text { Yellow } & \text { Red } & \text { Green } & \text { White } & \text { Orange } \\\hline \text { Frequency } & 11 & 12 & 16 & 15 & 19 & 17\end{array}$
