Studied by 4 peopleZ-score
Standardized location of a data piece using the standard deviation representing how many standard deviations a data piece is above (positive) or below (negative) the mean
Z-score equation
X (what we got)−(x-bar (what we expected)/Sx (standard deviation))
Mean and st. dev of normal curve
Mean=0 St.dev=1
Empirical rule
Important empirical rule percentages
To find the area under a curve
Normalcdf(Lower bound, Upper bound, Mean, Standard Deviation)
To find the interval given the area
Invnorm(Percentage, mean, standard deviation, section of the curve (right, left, or center))
