The senior class president of a large university claimed that 65% of the senior class was interested in going on the senior trip. To test this claim, the senior class president conducted a survey of a random sample of 50 seniors and 41 said that they wanted to go on the senior trip. To better understand the significance of the survey results, a simulation was devised based on the claim that 65% of the seniors wanted to go on the trip, each of sample size 50, simulated 200 times. Explain how the results of the simulation can be used to support or refute the senior class president's claim.

Chapter 11 Worksheet on Regression Name Consider an experiment designed to estimate the linear relationship between the percentage of a certain drug in the bloodstream of a subject and the length of time it takes the subject to react to a stimulus. In particular, the researchers want to predict reaction time based on the amount of drug in the bloodstream. Give a practical interpretation of the slope. Give a practical interpretation of the coefficient of correlation. What percentage of the sample variation in y can be explained by x in the simple linear model? REACTIO PERCENT N TIME 4.5 XOF IN 4 DRUG SECONDS 3.5 y=0.7x-0.1 R = 0.8167/ 2 2.5 3 4 1.5 1 0.5 r^2=.8167 From Excel
