Nishant,
Here are the steps for enabling/disabling statistics for your domains.
Login to Plesk > Click on 'Domains' on the left menu > Click on the domain (lakesparadise.com) > Click on 'Setup' icon > Web statistics. Here you have an option to select from Webalizer or AwStats.
For now, I have enabled it for both of the domains provided by you. Also, I have enabled statistics management option for your account too.
If you still find it a problem, let us know & we'll do it for you in no time
