Find s squared and sigma squared are the sample and population variances.

use chi squared

identify the claim and stating the hypotheses.

write the null hypothesis and the alternative hypothesis.Since the claim does not include equality,

identify the P-value for the standardized test statistic to be used to determine whether the null hypothesis should be rejected or not.

To find the P-value, first identify the type of test.

Calculate the standardized test statistic using the formula below.

\fAn 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 $3700. A random sample of 25 total hospital charges for patients involved in this type of crash has a standard deviation of $4600. At of= 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. H: 0 $3700 O C. H: 0 > $3700 O D. H: 02 $3700 H_: $ $3700 H.: G
