1. HO: u = 90 Ha: u 90 The sample mean is 69 and the sample size is 35. The population follows a normal distribution with a standard deviation of 5. Use a = 0.05. 2. A survey reports the mean age at death in the Philippines is 70.95 years old. An agency examines 100 randomly selected deaths and obtains a mean of 73 years with a standard deviation of 8.1 years. At 1% level of significance, test whether the agency's data support the alternative hypothesis that the population mean is greater than 70.95.
