# answer following questions 30

1. On your way to school, identify a Discrete Random Variable and a potential problem associated to that variable (use your imagination). (a) Briefly, describe the variable and the problem. (b) Image the current situation of that variable (use a statistical measure) and describe it as your Null Hypothesis. (c) Imagine the situation where you expect the variable to be after research in done, and describe it as your Alternative Hypothesis.

*Note: For your two problems above, provide and interpret the expected mean value (or measure of central distribution of your choice), and the standard deviation (or measure of dispersion of your choice), within the context of the real-life examples that you have selected. Since you are using real examples, you should be able to provide practical numbers for the statistical measures.
