Use the provided contingency table and expected frequencies. At a = 0.10, test the hypothesis that the variables are independent. Complete parts (a) through (e) below. Result Injury 20 (24.524) No injury 186 (181.476) Stretched Athlete has Not stretched 30 (25.476) 184 (188.524) (a) Identify the claim and state Ho and Ha Ho: An athlete's injury result is independent of whether or not the athlete has stretched. Ha: An athlete's injury result is dependent on whether or not the athlete has stretched. Which hypothesis is the claim? Null hypothesis Alternative hypothesis (b) Determine the degrees of freedom, find the critical value, and identify the rejection region. Calculate the degrees of freedom. d.f. = 1 (Type a whole number.) Find the critical value. x6 =☐ (Round to three decimal places as needed.)
