This lesson corresponds to Chapter 3 in the Lock 5 textbook. In Lessons 2 and Lesson 3 you learned about descriptive statistics. Lesson 4 begins our coverage of inferential statistics which use data from a sample to make an inference about a population. Confidence intervals use data collected from a sample to estimate a population parameter.Step 1. 27.5% of US adults are college graduates. Click here to access StatKey.

12.2.1 - Hypothesis Testing. In testing the statistical significance of the relationship between two quantitative variables we will use the five step hypothesis testing procedure: 1. Check assumptions and write hypotheses. In order to use Pearson's r both variables must be quantitative and the relationship between x and y must be linear.Understanding and Interpreting the y-intercept. The y-intercept, a, of the line describes where the plot line crosses the y-axis.The y-intercept of the best-fit line tells us the best value of the relationship when x is zero. In some cases, it does not make sense to figure out what y is when x = 0. For example, in the third exam vs. final exam example, the y …
