A normal distribution has mean ( mu=61 ) and standard deviation ( sigma=20 ). Find and interpret the ( z )-score for ( x=54 ). The ( z )-score for ( x=54 ) is ( square ). So 54 is ( square ) standard deviations ( ( ) Choose one) ( abla ) the mean ( mu=61 ).

Step 1
A \( z \)-score is a measure that describes a value's relationship to the mean of a group of values. It is measured in terms of standard deviations from the mean. The formula to calculate a \( z \)-score is given by: \[ z = \frac{x - \mu}{\sigma} \] where \( x \) Show more…

The normal distribution has a mean μ = 56 and standard deviation σ = 20. Find and interpret the Z-score for x = 59. The Z-score for x = 59 is Z = (59 - 56) / 20 = 0.15. So, 59 is 0.15 standard deviations above the mean.

In a distribution of scores, $X=64$ corresponds to $z=1.00$, and $X=67$ corresponds to $z=2.00$. Find the mean and standard deviation for the distribution.
For a sample distribution of scores, X = 36 corresponds to a z-score of z = –1.25, and X = 42 corresponds to a z-score of z = –0.75. What are the values for the mean and standard deviation for the distribution?
