X would be continuous. There is not a finite number of miles you can
drive. Miles also can, or cannot be, whole numbers.
Y: the number of mailboxes you passed on the way to school today
Y would be discrete. You can only use whole numbers, and there is only
so many mailboxes you pass on your way to school.
(2) Sam is a representative who sells large appliances such as refrigerators, stoves, and
so forth. Let x = number of appliances Sam sells on a given day. Let f = frequency
(number of days) which he sells x appliances. For a random sample of 240 days,
Sam had the following sales record. Assume the sales record is representative of
the population of all sales for a day.
