Railroad tracks’ rails must be a precise distance from each other. If the distance between the rails is too narrow or too wide, the train will derail. Come prepared to discuss the following questions:
Imagine traveling back to 1865 when railroads were being built all across the American frontier. How do you think they built the tracks to be the right width apart from each other? What could have gone wrong? Could you teach the railroad workers about parallelism (alternate interior and exterior angles, etc.) so they could always build tracks the right width apart?
Do you think it would be practical to use principles of parallelism for building railroads during that time period? Why or why not?
What other methods could be used to ensure parallel rails (any method, not just the geometry kinds)?

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
