The mean age of a random sample of 13 registered Liberals is 43 years with a standard deviation of 7.5 years. The mean age of a random sample of 17 registered Conservatives is 38 years with a standard deviation of 3.5 years. We would like to determine if there is evidence that the true mean age of Conservatives is less than the true mean age of Liberals. What is the P-value for the appropriate test of significance? between 0.0025 and 0.005 between 0.005 and 0.01 O between 0.01 and 0.02 between 0.02 and 0.025 between 0.025 and 0.05 The mean age of a random sample of 13 registered Liberals is 43 years with a standard deviation of 7.5 years.
