A normal distribution has a mean of 104 and a standard deviation of 1.9.

What is the z-score of 108?

Work Shown:

x = 108 is the raw score we want to transform

mu = 104 is the mean

sigma = 1.9 is the standard deviation

z = (x-mu)/sigma

z = (108-104)/1.9

z = 4/1.9

z = 2.10526315789473 which is approximate

z = 2.11 rounding to two decimal places

I'm rounding to two decimal places because many z tables will work with this level of precision.

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
