Directions: Draw a conclusion from the given information. 1. Ho:μ = 80Ha:μ # 80The sample mean is 83, the sample size is 39, and the standard deviationis 5. Use a = 0.05.2. Ho: μ = 7.5Ha: μ > 7.5The sample mean is 8.3 and the sample size is 52. The population followsa normal distribution with standard deviation of 3.17. Use a = 0.01.3. Ho: μ = 10Ha: μ > 10The sample mean is 15, the sample standard deviation is 6.1, and thesample size is 9. Use a = 0.05.4. Ho:μ = 116.12 H:>116.12The population follows a normal distribution with standard deviation of7.18. The sample mean is 118.7 and the sample size is 21. Use a = 0. 01.5. Ho: μ = 215 Ha: μ # 215The population is approximately normal. The sample mean is 219.3, thesample standard deviation is 13.12, and the sample size is 22. Useα = 0.05.
