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 28 total hospital charges for patients involved in this type of crash has a standard deviation of $4100. At a = 0.10 can you support the agent's claim? Use the P-value method to test the claim, Hg: o< $3800 Ha: o> $3800 Identify the test statistic. 31.43 (Round to two decimal places as needed.) Identify the P-value. 0.746 (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 10% level of significance to support the insurance agent's claim. O B. Reject Ho. There is not enough evidence at the 10% level of significance to support the insurance agent's claim. O C. Fail to reject Hp. There is enough evidence at the 10% level of significance to support the insurance agent's claim. O D. Reject Ho. There is enough evidence at the 10% level of significance to support the insurance agent's claim.

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 28 total hospital charges for patients involved in this type of crash has a standard deviation of $4100. At a = 0.10 can you support the agent's claim? Use the P-value method to test the
claim.
Haio< $3800
.....
Ha: o > $3800
Identify the test statistic.
31.43 (Round to two decimal places as needed.)
Identify the P-value.
0.746 (Round to three decimal places as needed.)
Choose the correct conclusion below.
A. Fail to reject Ho. There is not enough evidence at the 10% level of significance to support the insurance agent's claim.
B. Reject Ho- There is not enough evidence at the 10% level of significance to support the insurance agent's claim.
O C. Fail to reject Ho. There is enough evidence at the 10% level of significance to support the insurance agent's claim.
O D. Reject Ho. There is enough evidence at the 10% level of significance to support the insurance agent's claim.
