The basic equation underlying exact tests is =: () ()where: x is the actual observed outcome,; Pr(y) is the probability under the null hypothesis of a potentially observed outcome y,T(y) is the value of the test statistic for an outcome y, with larger values of T representing cases which notionally represent greater departures from the null …
Webh = ttest(x) returns a test decision for the null hypothesis that the data in x comes from a normal distribution with mean equal to zero and unknown variance, using the one-sample t-test.The alternative hypothesis is that the population distribution does not have a mean equal to zero.
