Where "a" represents the slope and "b" represents the y-intercept. Note that this is different than the model we're using in class. To get these values move the cursor with the left arrow key until the cursor rests under the estimator of interest. Use the8. Find the details. TRACE and use left and right arrow keys. * P1:L1,L2 means this is Plot1 (scatterplot) with x –values (independent variable) in L 1 and y –values (dependent variable) in L 2. * Y=15 gives value of y variable when x variable is 526. TRACE and use up arrow keys to trace line. * Y1 means the regression line is being traced.A z-score tells us how many standard deviations away a given value is from the mean. The z-score of a given value is calculated as: z-score = (x - μ) / σ. where: x: individual value. μ: population mean. σ: population standard deviation. This tutorial explains how to calculate z-scores on a TI-84 calculator.Scatter Plots and Correlation: https://youtu.be/CeHtXupAGvsLinear Regression by Hand: https://youtu.be/KomP0HbvOsQ
