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 0.01 significance level, test the claim that injuries are independent of helmet color.

Red 169 72 Identify the null and alternative hypotheses. Choose the correct answer below. OA. Ho: Injuries and helmet color are dependent H₁: Injuries and helmet color are independent OB. Ho: Whether a crash occurs and helmet color are independent H₁: Whether a crash occurs and helmet color are dependent OC. Ho: Whether a crash occurs and helmet color are dependent H₁: Whether a crash occurs and helmet color are independent OD. Ho: Injuries and helmet color are independent H₁: Injuries and helmet color are dependent Blue 62 30 D Compute the test statistic. 0 (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 s 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.
