Finding z value and probability under standard normal curve
Not what you're looking for?
1A. For a normal distribution that has a mean of 100, and a standard deviation of 8, determine the Z-score for each of the following X values
X = 108 Z=
X = 112 Z =
X = 98 Z =
X = 70 Z =
X = 124 Z =
1B. Use the information in 1 A. to determine the area or probability of the following p(x > 108)
p(x < 98)
p(92 < x < 108)
p(84 < x < 116)
p(x < 84)

Solution Summary
The solution gives detailed steps on finding z value and probability under a standard normal curve.
Solution Preview
Now z=(x-mean)/sd
X = 108 Z=(108-100)/8=1
X = 112 Z =(112-100)/8=1.5
X = 98 Z ...
