Finds the value corresponding to a given cumulative probability.
Use the formula: X=μ+ZσX = \mu + Z\sigmaX=μ+Zσ with given area, μ\muμ, σ\sigmaσ.
Input Area: 0.580.580.58 as it equals 1−0.421 - 0.421−0.42.
P(X≤c)=0.62+P(X≤24)=0.62+0.3085P(X \leq c) = 0.62 + P(X \leq 24) = 0.62 + 0.3085P(X≤c)=0.62+P(X≤24)=0.62+0.3085.
Use IPR=Q3−Q1IPR = Q3 - Q1IPR=Q3−Q1 for the specific percentiles.
Tom is correct; they are equal in a normal distribution.
z=(X−μ)/σz = (X - \mu) / \sigmaz=(X−μ)/σ, where XXX is the value of interest.
They indicate the number of standard deviations from the mean.
Use z=(6−μ)/σz = (6 - \mu) / \sigmaz=(6−μ)/σ and look up corresponding zzz-value.
Find zzz for 0.30.30.3, then use σ=(22−μ)/z\sigma = (22 - \mu) / zσ=(22−μ)/z.
