Standard normal-distribution table & how to use instructions to find the critical value of Z at a stated level of significance (α) for the test of hypothesis in statistics & probability surveys or experiments to large samples of normally distributed data. Examine the table and note that a "Z" score of 0.0 lists a probability of 0.50 or 50%, and a "Z" score of 1, meaning one standard deviation above the mean, lists a probability of 0.8413 or 84%. In short, yes, a negative mean value is feasible with a curve which is normally distributed.
