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 α=0.10 .
$\begin{array} { l | c c c c c c }
\text { Color } & \text { Blue } & \text { Yellow } & \text { Red Green } & \text { White Orange } \
\hline \text { Frequency } & 12 & 11 & 17 & 16 & 19 & 15
