Question How to find out whether a process is dead or alive from within a shell script file

I am writing a shell script to a file. The script -after somehow being provided with a process id- should kill it after determining that the process is up and running. I need to a way to silently (i.e, without printing output to the standard output) determines whether the process is running or not... I looked up the man page for ps but did not see any option/flag that would allow this silently... Anybody knows of a way?

ps -A | grep -q <process ID>

if [ $? -eq 0 ]
I'm using that in a script, and I don't get any output, whether the process exists or not.
