A concrete beam may fail either by shear (S) or flexure (F). Suppose that three failed beams are randomly selected and the type of failure is determined for each one. Let X the number of beams among the three selected that failed by shear. List each outcome in the sample space along with the associated value of X.
STATS 10 Week 3 Notes: Chapter 4 Lecture 6 Chapter 2: graphically summarize numerical/categorical data Chapter 3: describe a numerical variable's center and spread when its distribution is symmetric/skewed Chapter 4: linear relationship between two numerical variables using statistics and a linear equation We always begin with a graph. Scatterplot Dot plot for 2 numerical variables. Can see patterns, trends, relationships, and sometimes outliers. explanatory/independent variable: x-axis variable response/dependent variable: y-axis variable Direction From lower left to upper right is positive (x+, y+) From upper left to lower right is negative (x+, y-) Shape If the points look like they're stretched out generally and consistently in a straight form, the relations
