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 $3800. A random sample of 22 total hospital charges for patients involved in this type of crash has a standard deviation of $4100. At a = 0.05 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: os $3800 Ha: o> $3800 O B. Ho: o> $3800 Ha: os $3800 OC. Ho: o< $3800 O D. Ho: o2 $3800 Ha: 02 $3800 Ha: o< $3800 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. O (Round to three decimal places as needed.) Choose the correct conclusion below. O A. Fail to reject Ho. There is not enough evidence at the 5% level of significance to support the insurance agent's claim. O B. Reject Ho. There is enough evidence at the 5% level of significance to support the insurance agent's claim. OC. Fail to reject Ho. There is enough evidence at the 5% level of significance to support the insurance agent's claim. O D. Reject Ho. There is not enough evidence at the 5% level of significance to support the insurance agent's claim.
