CONTINUOUS RANDOM VARIABLES

1.Mr. Jackson will announce the student he selected during today's Math Club meeting. The meeting starts at 11:30 a.m. and ends at noon. The exact time of the announcement will be completely random.

Part A:Answer these questions about the announcement time.(6 points: 2 points for each correct answer)

1. Why is the time of the announcement an example of a continuous random variable?
2. What is the sample space?
3. What will be the shape of the density graph for these data? How do you know?

Part B: this density graph to show the probability distribution of the announcement time data.(8 points)
