It will overwrite itself each time a LSRL is calculated.Residual Plot: Follow the steps for graphing a scatterplot above, however, change the y-list to the residual list (2nd STAT, Choose RESID)ProbabilityNormal Probability: Find z-score(s) first, showing work on your paper. Draw a sketch if it helps you. 2nd VARS, 2:nromalcdf, Enter lower z-score, higher z-score, leave μ = 0 and σ = 1, Paste, ENTERInverse Normal: The inverse normal command will report the z-score associated with a particular area under the curve. Draw a sketch to represent the situation. 2nd VARS, 3:invNorm, Next to area type the amount of area to the left (regardless of where you shaded), leave μ = 0 and σ = 1, Paste, ENTER. You will likely still have some Algebra to do with this reported z-score.Discrete Expected Value and Standard Deviation: Remember, you still have to show the work on your paper, so make sure you understand the formula. STAT, Edit…, Enter x’s into L1 and P(x) into L2, STAT, Scroll to CALC, 1:1-VarStats, List = L1, FrqList = L2, CalculateBinomial Probability for a Single x-Value: Remember, you still have to show substitution into the formula on your paper. 2nd VARS, binompdf, trials = n, p = probability of success on any given trial, x value = whatever # of successes you are trying to find probability for, Paste, ENTERBinomial Probability for Multiple x-Values Summed Together: ALPHA, WINDOW, 2: Σ( . Type into formula filling in the smallest x-value, largest x-value, n, and p. Leave x as a variable (use X,T,θ,n key)Geometric Probability for a Single Value: Remember, you still have to show substitution into the formula on your paper. 2nd VARS, geometpdf, p = probability of success on any given trail, x value = whatever trial # you are looking for success on, Paste, ENTERGeometric Probability for Multiple x-Values Summed Together: ALPHA, WINDOW, 2: Σ( Type into formula filling in the smallest x-value, largest x-value, and p. Leave x as a variable (use X,T,θ,n key)InferenceInference procedures: STAT, Scroll to TESTSThe menus for each test are pretty self-explanatoryFor the 2-sample t-procedures, Pooled = NO ................
