Section 3.3 Bootstrap Confidence Intervals
Problem: In practice, only one sample is taken. So how do we obtain a sampling
distribution?
Solution: _ can be used to simulate a sampling distribution.

Section 2.6 Linear Regression
Example: evening temperature (y) vs. cricket chirps per minute (x)
A regression line is
A straight line that best fits the data in the scatterplot
The general form for the equation of a regression line:
^
Y= a+bx
A= intercept
Section 2.5 Scatterplots and Correlation
A scatterplot is
The graph of the relationship between two quantitative variables
Example: GPA (y) vs. Number of Hours Spent Studying Per Week (x)
