Sarah has just arrived at her job as a checker at a grocery store. The previouschecker states that he only had one customer in the last 15 minutes. Sarah’s shift is pretty slow so she starts towonder, “When did this customer arrive in the last 15 minutes? Did the customer arrive right at the beginningof 15 minutes (0), in the middle of the 15 minute time period or right at the end (15)?” She realizes that thetime of arrival for the customer is a random variable X that has a uniform distribution from 0-15 minutes andthat the likelihood they arrived at any time during the last 15 minutes is equally probable.a. (3 points) Draw the distribution for X from 0 to 15. Make sure to label you axes and give theheight of your density “curve”. b. (3 points) What is the probability the customer arrived within the first 3 minutes of the 15minute time interval? Draw a picture. P(X<3)= c. (3 points) What is the probability the customer arrived within the last 5 minutes of the 15minute time interval? Draw a picture. P(X>10)= 8
