    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/stats-base-ztest-two-sample-results-to-string
```

<section class="usage">

## Usage

```javascript
var res2str = require( '@stdlib/stats-base-ztest-two-sample-results-to-string' );
```

#### res2str( results\[, options] )

Serializes a two-sample Z-test results object as a formatted string.

```javascript
var Float64Results = require( '@stdlib/stats-base-ztest-two-sample-results-float64' );

var results = new Float64Results();

// ...

var s = res2str( results );
// returns <string>
```

The function supports the following parameters:

-   **results**: two-sample Z-test results object.
-   **options**: function options.

The function supports the following options:

-   **digits**: number of digits to display after decimal points. Default: `4`.
-   **decision**: boolean indicating whether to show the test decision. Default: `true`.

## Notes

-   Example output:

    ```text

    Two-sample Z-test

    Alternative hypothesis: True difference in means is less than 1.0

        pValue: 0.0406
        statistic: 9.9901
        95% confidence interval: [9.7821, 10.4451]

    Test Decision: Reject null in favor of alternative at 5% significance level
