Test statistic p-values, returned as a numeric scalar or vector with length equal to the number of tests. vratiotest returns pValue when you supply the input res. p-values are standard normal probabilities. stat— Test statistics numeric scalar | numeric vector Test statistics, returned as a...
tis the t-test statistic value (t = -25.55), dfis the degrees of freedom (df= 9), p-valueis the significance level of the t-test (p-value = 1.03910^{-9}). conf.intis the confidence interval of the mean of the differences at 95% (conf.int = [-217.1442, -181.8...
The p-value is equal to one minus the area under the curve corresponding to the chi-square test statistic. So, the p-value can be computed by subtracting 0.90 from 1:P=1−0.90=0.10. Hence, the p-value is 0.10. Example 2 A high school senior is analyzing...
