Given the following hypotheses: Ηρ: μ = 520 Η₁: μ ≠ 520 A random sample of 18 observations is selected from a normal population. The sample mean was 529 and the sample standard deviation 5. Using the 0.01 significance level: Required: a. State the decision rule. Note: Negative amount should be indicated by a minus sign. Round your answers to 3 decimal places. Reject Ho when the test statistic is outside the interval ( b. Compute the value of the test statistic. Note: Round your answer to 3 decimal places. Value of the test statistic

A sample of 37 observations is selected from a normal population. The sample mean is 25, and the population standard deviation is 5. Conduct the following test of hypothesis using the 0.05 significance level. H0: μ ≤ 24 H1: μ > 24 a. Is this a one- or two-tailed test? "One-tailed" - the alternate hypothesis is in the greater than direction. "Two-tailed" - the alternate hypothesis is different from the direction. b. What is the decision rule? (Round your answer to 3 decimal places.) Do not reject Reject H0, when z > c. What is the value of the test statistic? (Round your answer to 2 decimal places.) Value of the test statistic d. What is your decision regarding H0? Do not reject Reject There is insufficient sufficient evidence to conclude that the population mean is greater than 24. e. What is the p-value? (Round your answer to 4 decimal places.) p-value

A sample of 64 observations is selected from a normal population. The sample mean is 215, and the population standard deviation is 15. Conduct the following test of hypothesis using the 0.025 significance level. a. Is this a one- or two-tailed test? One-tailed test Two-tailed test What is the decision rule? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) Reject Do not reject H0 when z < c. What is the value of the test statistic? (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Value of the test statistic d. What is your decision regarding H0? Do not reject Reject e. What is the p-value? (Round your answer to 4 decimal places.) p-value

A sample of 30 observations is selected from a normal population. The sample mean is 59, and the population standard deviation is 8. Conduct the following test of hypothesis using the 0.02 significance level. H0: μ = 62 H1: μ ≠ 62 a. Is this a one- or two-tailed test? One-tailed test Two-tailed test b. What is the decision rule? Reject H0 if z < -2.326 or z > 2.326 Reject H0 if -2.326 < z < 2.326 c. What is the value of the test statistic? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) d. What is your decision regarding H0? Fail to reject H0 Reject H0 e. What is the p-value? (Round z value to 2 decimal places and final answer to 4 decimal places.)
