An insurance agent says the standard deviation of the total hospital charges for patients involved in a crash in which the vehicle struck a construction barricade is less than $3600. A random sample of 20 total hospital charges for patients involved in this type of crash has a standard deviation of $4100. At a = 0.01 can you support the agent's claim? Use the P-value method to test the claim. Identify the null and alternative hypotheses. Let o be the population standard deviation. O A. Ho: as $3600 O B. Ho: a > $3600 H : G> $3600 H: a's $3600 M C. Ho: 0 2 $3600 O D. Ho: a 15.9 Find the critical value(s) and determine the rejection region. Select the correct and below and fill in the corresponding answer box(es) to complete your choice. (Round to three decimal places as needed.) A. x2 > 55.758 O B. OD. X2
