Directions: Draw a conclusion from the given information.

1. Ho:μ = 80 Ha:μ # 80 The sample mean is 83, the sample size is 39, and the standard deviation is 5. Use a = 0.05. 2. Ho: μ = 7.5 Ha: μ > 7.5 The sample mean is 8.3 and the sample size is 52. The population follows a normal distribution with standard deviation of 3.17. Use a = 0.01. 3. Ho: μ = 10 Ha: μ > 10 The sample mean is 15, the sample standard deviation is 6.1, and the sample size is 9. Use a = 0.05. 4. Ho:μ = 116.12 H:>116.12 The population follows a normal distribution with standard deviation of 7.18. The sample mean is 118.7 and the sample size is 21. Use a = 0. 01. 5. Ho: μ = 215 Ha: μ # 215 The population is approximately normal. The sample mean is 219.3, the sample standard deviation is 13.12, and the sample size is 22. Use α = 0.05.
