What determines the variance? Skewness or deviation?
Athletes are testing new models of running shoes, 50% will test type A, 50% will test type B - method to perform the analysis? Individual T/Z scores or pooled? Two questions on determining the SD for three groups of numbers, you need to pick the group with the highest deviation. MUST know the standard error formula, correlation/regression. 6 cars on the truck with 6 positions - possible combinations? Range from 300 to 720. Anova questions (when to use, -R, R^2, SD what determines the variance). Pr of driving from Town A to B is 0.60, Pr of taking a train is 0.2 - total Pr of taking either? What type of variable is height, weight, eye color, and age?
Null hypothesis (complex, pick the right scenario etc.).
