T test hypothesis table
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.
