Two-sample *t*-test

returns
a test decision for the null hypothesis that the data in vectors `h`

= ttest2(`x`

,`y`

)`x`

and `y`

comes
from independent random samples from normal distributions with equal
means and equal but unknown variances, using the two-sample *t*-test.
The alternative hypothesis is that the data in `x`

and `y`

comes
from populations with unequal means. The result `h`

is `1`

if
the test rejects the null hypothesis at the 5% significance level,
and `0`

otherwise.

returns
a test decision for the two-sample `h`

= ttest2(`x`

,`y`

,`Name,Value`

)*t*-test with
additional options specified by one or more name-value pair arguments.
For example, you can change the significance level or conduct the
test without assuming equal variances.
