feed awk positional parameters

Question

Can someone please help me with a script that takes a list of integers and returns a response with the average, total, maximum and minimum values?

I need to be able to pass parameters when I run the script e.g:

./script.sh 1 2 3 4 5

I have an awk script that does the average, total and maximum sorted, I just need to add a bit so that it will read the arguments - so when I run ./script.sh 1 2 3 4 it returns:

Average: 3
Min: 1
Max: 5
Total: 16

Any help would be appreciated.

This is what I have already:

#!/bin/bash

awk 'NR == 1 { max=$1; min=$1; sum=0 }
        { if ($1>max) max=$1; if ($1<min) min=$1; sum+=$1;}
        END {printf "Min: %d\nMax: %d\nAverage: %d\nSum %0.0f\n", min, max, sum/NR, sum}'

Thanks in advance!
