What statement is incorrect regarding the z-statistic and the z-critical when taking a sample in order to estimate the Mean of a population? The z-statistic is the z-value determined by subtracting the hypothesis mean from the mean of the sample data and dividing by the standard error The standard error is the standard deviation divided by the square root of the # of sample points z-critical is at the edges of the confidence interval: negative z-critical is the left edge and positive z-critical is the right edge If a positive z-statistic is less than the positive z-critical, we reject the Null hypothesis
