You may need to use the appropriate appendix table or technology to answer this question. A sample of 25 bottles of soft drink showed a variance of 0.49 in their contents. At the 5% level, determine whether or not the standard deviation of the population is significantly different from 0.6 ounces. Use the critical value approach. State the null and alternative hypotheses (in ounces ). (Enter ! = for # as needed.) HO: Find the value of the test statistic. (Round your answer to three decimal places.) State the critical value(s) for the rejection rule. (Round your answer(s) to three decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic > What is your conclusion? O Do not reject Ho. We can conclude that the population standard deviation is significantly different from 0.6 ounces. O Reject Ho. We cannot conclude that the population standard deviation is significantly different from 0.6 ounces. O Reject Ho. We can conclude that the population standard deviation is significantly different from 0.6 ounces. O Do not reject H . We cannot conclude that the population standard deviation is significantly different from 0.6 ounces.You may need to use the appropriate appendix table or technology to answer this question. A random sample of 22 observations showed a standard deviation of 9. At a 0.05 level of significance, test to see if the variance of the population is significantly less than 82. Use the critical value approach. State the null and alternative hypotheses. (Enter != for # as needed.) Ho: Find the value of the test statistic. (Round your answer to three decimal places.) State the critical value(s) for the rejection rule. (Round your answer(s) to three decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic 2 What is your conclusion? O Do not reject H. We cannot conclude that the population variance is significantly less than 82. O Reject H. We can conclude that the population variance is significantly less than 82. O Do not reject H. We can conclude that the population variance is significantly less than 82. O Reject Ho. We cannot conclude that the population variance is significantly less than 82.You may need to use the appropriate technology to answer this question. A large company has claimed that the standard deviation of the monthly incomes of their employees is less than or equal to $120. To test their claim, a random sample of 86 employees of the company was taken; and it was determined that the standard deviation of their incomes was $133. Using it : 0.10, test the company's claim. State the null and alternative hypotheses (in dollarsz). (Enter !: for as needed.) H0: H : a Find the value of the test statistic. (Round your answer to three decimal places.) E Find the pavalue. (Round your answer to four decimal places.) What is your conclusion? 0 Reject H0. The sample results do not support the company's claim. 0 Do not reject H0. The sample results do not support the company's claim. 0 Reject H0. The sample results support the company's claim. 0 Do not reject H0. The sample results support the company's claim. You may need to use the appropriate technology to answer this question. The average score of a sample of 41 students on their second statistics examination was 88 with a standard deviation of 13. Is the variance of the population significantly more than 100? Use a 0.05 level of significance. State the null and alternative hypotheses. (Enter != for # as needed.) Ho H.: Find the value of the test statistic. Find the p-value. (Round your answer to four decimal places.) p-value = What is your conclusion? O Reject Ho. We cannot conclude that the population variance is significantly more than 100. O Reject Ho. We can conclude that the population variance is significantly more than 100. O Do not reject H. We can conclude that the population variance is significantly more than 100. O Do not reject H . We cannot conclude that the population variance is significantly more than 100
