(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. 0. 1 2. 4 9. 6. 72 63 41 28 14 8. (a) Use the relative frequency to find P(x) for x = 0 to 7. Rdund these probabilities to 3 decimal places. P(x) 0.038 X F 6. 0200

Transcribed Image Text:(d) Compute the probability that x is less than 3.
Transcribed Image Text:and explain why you classify it as such.
X: the number of miles per month each student drives in this class
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.
