(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. 1 5 14 3. 4. 6. 7 72 63 41 28 8. (a) Use the relațive frequency to find P(x) for x-0 to 7. Round these probabilities to 3 decimaliplaces. P(x) 6. 72 63 41 28 14 8 (b) Use a histogram to graph the probability distribution of part (a). This may be hand-drawn or created electronically. This process is illustrated in example 1 on page 183. (c) Compute the probability that x is between 2 and 5 (including 2 and 5).
