ACTIVITY A. Directions: Determine the test statistic used. Then, find the value of the following based on the given information. 1. Ho: p=85 Ha: 85 The sample mean is 83, the sample size is 39, and the standard deviation is 5. Use a= 0.05. 2. Ho: p= 7.5 Ha: u> 7.5 The sample mean is 8.3 and the sample size is 52. The population follows a normal distribution with standard deviation 3.17. Use a = 0.01. 3. Ho: = 15 Hau< 15 The sample mean is 10, the sample standard deviation is 6.1, and the sample size is 9. Use a= 0.05. 4. Ho: p=116.12 Ha: > 116.12 The population follows a normal distribution with standard deviation of 7.18, sample mean of 118.7, and sample size of 21. Use a = 0.10.
