Find level of significance

WebTo determine whether any of the differences between the means are statistically significant, compare the p-value to your significance level to assess the null hypothesis. The null hypothesis states that the population means are all equal. Usually, a significance level (denoted as α or alpha) of 0.05 works well. WebIn the spreadsheet below, the Excel Confidence Function is used to calculate the confidence interval with a significance of 0.05 (i.e. a confidence level of 95%), for the mean of a sample of heights of 100 men. The sample mean is 1.8 meters and the standard deviation is 0.07 meters. The above function returns a confidence value of 0.013719748.
