Webz-Scores establish relationships between score, mean, standard deviation Example o Population: μ = 65 and X = 59 corresponds to z = -2.00 o Subtract 65 from 59 and find deviation score of six points corresponds to z value of -2.00 o (X - μ) / z = σ Example o Population: σ = 4 and X = 33 corresponds to z = +1.50 WebA z-score measures exactly how many standard deviations above or below the mean a data point is. Here's the formula for calculating a z-score: z=\dfrac {\text {data point}-\text {mean}} {\text {standard deviation}} z = standard deviationdata point − mean. Here's the …

Answered over 90d ago WebThe z-score is z = -1.18 Step-by-step explanation Given condition is: P (Z < z) = 0.119 What we need to find here is the z-score that corresponds to the area 0.119 to the left of z. Using the Standard Normal Cumulative Probability Table or technology, the required z-score is: P (Z < -1.18) = 0.119 Therefore, the z-score is z = -1.18 WebMath Statistics Use the standard normal table to find the z-score that corresponds to the given percentile.
