The mean of a set of data is 108.06 and its standard deviation is 115.45. Find the z score for a value of 489.67. Round to two decimal places as needed.

The z-score for the value 489.67 is 3.31.

Step-by-step explanation:

If X N (µ, σ²), then , is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z N (0, 1).  

The distribution of these z-variate is known as the standard normal distribution.

The information provided is:

μ = 108.06

σ = 115.45

Compute the z-score for the raw score X = 489.67 as follows:

Thus, the z-score for the value 489.67 is 3.31.

there is no

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
