Problem 26

More predictions Hurricane Katrinas hurricane force winds extended 120 miles from its center. Katrina was a big storm, and that affects how we think about the prediction errors. Suppose we add 120 miles to each error to get an idea of how far from the predicted track we might still find damaging winds. Explain what would happen to the correlation between Prediction Error and Year, and why

Step-by-Step Solution:
Step 1 of 3

Note: Pop. is short for Population Quick review sampling/sample size: the number of observations in a sample. We take a sample from the population. Law of Averages: Averages and proportions vary less from the “expected” as sample size increases;the statistical tendency toward a fixed proportion in the results when an experiment is repeated a large number of times Ex: Toss a coin 100 timespercentage of heads (not the # of heads) gets closer to 50% # of heads = half the # of tosses + chance error  chance error: likely to become larger as # of tosses increases, but likely to be small when compared to the total number of tosses. So, as sample size the precision in predicting from the expected
