0. 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 $4000. A random sample of 20 total hospital charges fo involved in this type of crash has a standard deviation of $4800. 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: <$4000 H₂:02 $4000 OC. Ho: as $4000 H₂:a>$4000 Identify the standardized test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.)

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 $4000. A random sample of 20 total hospital charges for patients
involved in this type of crash has a standard deviation of $4800. 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.
OA. Ho: <$4000
H₂:02 $4000
OC. Ho: as $4000
H₂:a>$4000
Identify the standardized test statistic.
(Round to two decimal places as needed.)
Identify the P-value.
(Round to three decimal places as needed.)
Choose the correct conclusion below.
OB. Ho: > $4000
H₂: os $4000
O D. Ho: $4000
H₂:<$4000
OA. Fail to reject Ho. There is enough evidence at the 5% level of significance to support the insurance agent's claim.
OB. Fail to reject Ho. There is not enough evidence at the 5% level of significance to support the insurance agent's claim.
OC. Reject Ho. There is enough evidence at the 5% level of significance to support the insurance agent's claim.
OD. Reject Ho. There is not enough evidence at the 5% level of significance to support the insurance agent's claim.
