One-sample and paired-sample *t*-test

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

= ttest(`x`

)`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. 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 paired-sample `h`

= ttest(`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 a one-sided
test.
