/**
* Computes a two-sample Z-test for two single-precision floating-point strided arrays.
*
* @param {PositiveInteger} NX - number of indexed elements in `x`
* @param {PositiveInteger} NY - number of indexed elements in `y`
* @param {(integer|string)} alternative - alternative hypothesis
* @param {number} alpha - significance level
* @param {number} diff - difference in means under the null hypothesis
* @param {PositiveNumber} sigmax - known standard deviation of `x`
* @param {Float32Array} x - first input array
* @param {integer} strideX - stride length for `x`
* @param {PositiveNumber} sigmay - known standard deviation of `y`
* @param {Float32Array} y - second input array
* @param {integer} strideY - stride length for `y`
* @param {Object} out - output results object
* @returns {Object} results object
*
* @example
* var Float32Array = require( '@stdlib/array/float32' );
* var Results = require( '@stdlib/stats/base/ztest/two-sample/results/float32' );
*
* var x = new Float32Array( [ 4.0, 4.0, 6.0, 6.0, 5.0 ] );
* var y = new Float32Array( [ 3.0, 3.0, 5.0, 7.0, 7.0 ] );
*
* var results = new Results();
* var out = sztest2( x.length, y.length, 'two-sided', 0.05, 0.0, 1.0, x, 1, 2.0, y, 1, results );
* // returns {...}
*
* var bool = ( out === results );
* // returns true
