a the formula for confidence level is xtsn12 we already know that the sample n isincreasing and all the other data remains the same so increasingthe value of n means that the value of n12 in theabove expression will be higher So when the division of the abovedata with the increase value of n is done the confidence levelwill decrease You are dividing for example 10 3 instead of 10 2 so thats why the confidence intervall will decrease as thesample size is increasedbSystematic error can be located and minimized with carefulanalysis and design of the test conditions and procedure bycomparing your results to other results See Answer
