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.
Questions: Compute the test statistic (Round to three decimal
places as needed.) and find the critical value. Please list steps.
