C++ Program to implement standard error of mean

In this tutorial, we will be discussing a program to implement standard error of mean.

Standard error of mean is the estimation of sample mean dispersion from population mean. Then it is used to estimate the approximate confidence intervals for the mean.

Example

#include 
using namespace std;
//calculating sample mean
float calc_mean(float arr[], int n){
   float sum = 0;
   for (int i = 0; i 

Output
0.8063
