rails check_box_tag set checked with default value

Question

I currently have a rails check_box_tag call that looks like

check_box_tag #{name}

I want to include a checked attribute, which I know I can do

Answer 1

check_box_tag(name, value = "1", checked = false, options = {})

Examples:

check_box_tag 'receive_email', 'yes', true
# => 

check_box_tag 'tos', 'yes', false, class: 'accept_tos'
# => 

check_box_tag 'eula', 'accepted', false, disabled: true
# =>
