Answer 3

#include <iostream>

using namespace std;

int main() {
int numInputs;

cout << "how many numbers in the data set?" << endl;
cin >> numInputs;

float arr[numInputs];
float sum = 0;
cout << "Enter List of numbers" << endl;

for(int i = 0; i < numInputs; i++){
cin >> arr[i];
sum += arr[i];
}
float mean;
mean = sum / numInputs;
cout << "Arithmetic Mean: " << mean << endl;
return 0;
}
