A case-control (or retrospective) study was conducted to investigate a relationship between the colors of helmets worn by motorcycle drivers and whether they are injured or killed in a crash. Results are given in the accompanying table. Using a 0.05 significance level, test the claim that injuries are independent of helmet color. Color of Helmet Black White Yellow Red Blue Controls (not injured) 480 357 27 155 87 Cases (injured or killed) 211 104 7 63 42 Click here to view the chi-square distribution table. O C. Ho: Injuries and helmet color are dependent H1: Injuries and helmet color are independent O D. Ho: Injuries and helmet color are independent H1: Injuries and helmet color are dependent Compute the test statistic. (Round to three decimal places as needed.) Find the critical value(s). (Round to three decimal places as needed. Use a comma to separate answers as needed.) What is the conclusion based on the hypothesis test? Ho. There sufficient evidence to warrant rejection of the claim that injuries are independent of helmet color
