Or when the hypothesized mean is k and the standard deviation is s: The P-value is calculated using the one sample t-test, with the value t calculated as: The P-value is the probability of obtaining the observed mean in the sample if the null hypothesis value were the true value. A significance value (P-value) and 95% Confidence Interval (CI) of the observed mean is reported. This procedure calculates the difference of an observed mean with a hypothesized value. Test mean is equal to: enter the value to compare the mean to.The observed sample mean, standard deviation and sample size (n).The Test for one mean can be used to test the hypothesis that a sample mean is equal to a given mean (with unknown standard deviation) or certified value.
