Websmall samples, z can be replaced by t-value obtained from the Student's t-distribution tables [14]. The value of t corresponds to n 1. For example, for: – n=6, – mean=101.82, – standard deviation=1.2, – 95% confidence interval=0.49. So, this calculated confidence interval indicates that the range of the true population of the mean is ... WebThere are different types of precision, depending on the conditions under which precision is determined, e.g. repeatability (section 1) and intermediate precision (section 6). …
