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 25 total hospital charges for patients involved in this type of crash has a standard deviation of $4000. At a = 0.10 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. OA. Ho: o≤ $3600 Ha: σ> $3600 OC. Ho: o>$3600 Ha: o≤ $3600 Identify the standardized test statistic. (Round to two decimal places as needed.) σ OB. Ho: <$3600 H₂: 0≥ $3600 D. Ho: 0≥ $3600 H₂: σ<$3600 nc
