If an array looks like this:
$answers = array( 'gender', 'age', 'income', 'home', 'time_online', 'it_knowhow', 'online_buys')
Will the values to each key be NULL?

An array key can never be NULL, otherwise it would completely defeat the point of having an array.
If you don't define the key (as in your example above), it will automatically be created starting at 0. Giving you the keys as stated by Laler
