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 a 1% level of significance, test whether the agency's data support the alternative hypothesis that the population means is greater than 70.95. 2. The mean time a customer waits in line before checking in a grocery chain is less than 10 minutes. To verify the performance of the store, the obtaining mean time of 25 customers is 9.5 minutes with a standard deviation of 1.6 minutes. Use these data to test the null hypothesis that the mean time is 10 minutes, at a 0.01 level of significance.When the value of sample size (n)... n 2 30 1
