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 16 of the time. A student suspects that a certain spinner is defective. The suspected spinner is spun 90 times. The results are shown below. Find the critical value χ2α to test the student's claim. Use α=0.10. Round to three decimal places. Color Blue Yellow Red Green White Orange Frequency 11 15 17 19 16 12
