Substituting select option in Angular.js

I am trying to substitute, the drop down options “Yes/No” to true and false so that I can make usage of ng-hide to make the appearance of an input field dynamic. But the binding is not working as desired. Please check the JS bin link https://jsbin.com/piteqoduba/1/edit?html,output and advise.

<div ng-app="myApp" ng-controller="myCtrl">
<p>Delivery to same address?</p>
<ng-int="selectedVal={range.value}"></ng-int>
<select ng-model="selectedVal" ng-options="range.display for range  in range" >

</select>
<p  ng-hide= "selectedVal" >Fill your address below.</p>
<input type="text" ng-hide = "selectedVal">
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.range = [{display: "yes", value:true},
       {display: "no", value: false}
       ];
});
</script>
