Among 30children (aged five to six years) living in a particular neighborhood, thestandard deviation of diastolic blood pressure is 7.9mm Hg and the meandiastolic blood pressure is 56.2mm Hg. A national study indicates that the meandiastolic blood pressure is 64.2 mm Hg for children aged five to six years. Isthere evidence that the mean diastolic blood pressure for children in theneighborhood differs from the national mean diastolic blood pressure forchildren aged five to six years? Any thoughts on how to approach this question?I am not sure what topic the question falls under. Thanks.
