An article in Journal of Structural Engineering presents the results of an experiment that evaluated a standard method for estimating the brace force for a truss. In a sample of 360 short test trusses the method underestimated the force for 45 of them, and in a sample of 400 long test trusses, the method underestimated the force for 60 of them. Find a 95% confidence interval for the difference between the underestimation rates for long and short trusses.

Outline your experiment. You will NOT have to actually perform the experiment, you are just creating the structure of the experiment you would perform to test whether your superstition (lucky shirt) is “true”. Dependent variable - Whether or not you feel lucky. Independent variable - Shirt ('Regular' or 'Lucky') QUESTION: In one or two brief but clearly written paragraphs, describe how you would conduct this experiment. Include operational definitions, number of participants, where the experiment would take place (High School),...

Perform an Internet search and locate an article that discusses the pros and cons of a trade agreement (NAFTA or USMCA, European Economic Area, TPP, MERCOSUR, etc.). Please be sure to use a reputable news source, such as Bloomberg, Forbes, BBC, etc. You may need to use two sources (for example, CNN and FOX) in order to obtain information on both pros and cons. A news article will often be biased and cite only the pros, but not the cons...
