Many track hurdlers believe that they have a better chance of winning if they start in the inside lane that is closest to the field. For the data below, the lane closest to the field is Lane 1, the next lane is Lane 2, and so on until the outermost lane, Lane 6. The data lists the number of wins for track hurdlers in the different starting positions. Find the critical value ya to test the claim that the probabilities of winning are the same in the different positions. Use of = 0.05 and round to three decimal places. The results are based on 240 wins Starting Position 1 2 3 4 6 9 Number of Wins 3 36 32 44 45 50 O A. 9.236 O B. 15.086 O C. 12.833 O D. 11.070 12. A company wants to determine if its employees have any preference among 5 different health plans which it offers to them. A sample of 200 employees provided the data below. Find the critical value ya to test the claim that the probabilities show no preference. Use a = 0.01. Round to three decimal places.

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 - 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 ya to test the student's claim. Use a = 0.10. Round to three decimal places. Color Blue Yellow Red Green White Orange Frequency 16 17 19 11 15 12 O A. 9.236 O B. 10.645 O C. 1.610 O D. 11.071 14. A random sample of 160 car purchases are selected and categorized by age. The results are listed below. The age distribution of drivers for the given categories is 18% for the under 26 group, 39% for the 26-45 group, 31% for the 45-65 group, and 12% for the group over 65. Find the critical value ya to test the claim that all ages have purchase rates proportional to their driving rates. Use a = 0.05. Round to three decimal places. Age Under 26 26-45 46-65 Over 65 Purchases 66 39 25 30 O A. 11.143 O B. 9.348 O C. 7.815 O D. 6.251
