Question:
Lab 6.1 The Mean of a Discrete Random Variable In this lab, you will discuss how to calculate the mean for a discrete random variable. At Rushmore Community College, there have been complaints about how long it takes to get food from the college cafeteria. In response, a study was conducted to record the total amount of time students had to wait to get their food. The following table gives the total times (rounded to the nearest 5 minutes) to get food for 200 randomly selected students Time (minutes) 5 10 15 20 25 Number of students 30 52 62 40 16 1. Construct a probability distribution for the random variable X- "time to get food." x-Time 5 10 15 20 25 (minutes) P(x) 2. Graph the probability distribution. 3. Calculate the mean time to get food from the probability distribution in part 1
