An insurance agent says the standard deviation of the total bill for hospital patients who were involved in serious vehicles accidents was less than $17,800. A random sample of 29 bills had a standard deviation of $16,023. Test the claim with a 0.10 level of significance. 1. State the hypotheses and label the claim. Is the test left-tailed, right-tailed, or two-tailed? 2. What is/are the critical value(s)? Draw a picture. 3. What is the test-statistic? 4. State the conclusion. Give one reason for your decision to reject/not reject H0 based on: 5.Test statistic compared to critical value Then, relate back to the original claim.
