Q2 - A standard survey mark has the AMG coordinates 339,496.509E, 6,645,859.895N. A sample of 40 instantaneous position fixes from a GPS receiver gives a mean position (transformed to AMG coordinates) 339,499.538E, 6,645,855.509N with a standard deviation of 10.000 m.
A) Formulate null and alternative hypotheses to test the accuracy of the GPS coordinates against the SSM coordinates.
B) Test these hypotheses at a 99% confidence level.
C) From the result to part b) what can you infer about the accuracy of the SSM coordinates and the GPS coordinates?
My main problem is in relation to AMG (Australian Map Grid) co-ordinates vs SSM co-ordinates vs geographic (degrees) co-ordinates and formulas used for conversion. Any enlightenment on a suggested approach to this type of question would be greatly appreciated.
Also, if someone could provide me with links to websites that have good tutorials or information relating to Cartographic Statistics for a beginner, I would be very grateful.
