/**
* Computes a one-sample Z-test for a one-dimensional single-precision floating-point ndarray.
*
* ## Notes
*
* - The function expects the following ndarrays:
*
* - a one-dimensional input ndarray.
* - a zero-dimensional output ndarray containing a results object.
* - a zero-dimensional ndarray specifying the alternative hypothesis.
* - a zero-dimensional ndarray specifying the significance level.
* - a zero-dimensional ndarray specifying the mean under the null hypothesis.
* - a zero-dimensional ndarray specifying the known standard deviation.
*
* - The output ndarray's underlying results object is written to directly via a `DataView`, as the object's memory layout does not correspond to any ndarray-supported data type.
*
* @private
* @param {ArrayLikeObject<Object>} arrays - array-like object containing ndarrays
* @returns {ndarrayLike} output ndarray
