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. Identify the null and alternative hypotheses. Let a be the population standard deviation. OA Ho: a< $3800 OB. H9: o> $3800 H:os $3800 H:02 $3800 C. Ho: 02 $3800 OD. Hg: Gs $3800 H:o> $3800 H:a< $3800 Identify the test statistic. 28.45 (Round to two 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 $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.
Identify the null and alternative hypotheses. Let o be the population standard deviation.
O A. Ho: o< $3800
Ha:02 $3800
O B. Ho: o > $3800
Ha:os $3800
C. Ho: o $3800
Ha:o< $3800
O D. Ho: os$3800
Ha: o > $3800
Identify the test statistic.
