Find the z-score for which 8 percent of the distribution's area lies between -z and z?
To find the z-score where 8% of the distribution's area lies between -z and z, we first recognize that this means 4% (or 0.04) lies in each tail of the normal distribution. Therefore, we need to find the z-score that corresponds to the cumulative area of 0.04 in the left tail. Using standard normal distribution tables or a calculator, we find that the z-score for 0.04 is approximately -1.75. Thus, the positive z-score is approximately 1.75, meaning z ≈ 1.75.

How do you use a z table?
A z table is used to calculate the probability of choosing something that is normally distributed. In order to use it, first a z score is needed. A z score is the number of standard distributions a value is away from the mean of the data. In order to find the z score, take the value of the datum, subtract the mean, then divide by the standard deviation. The result is a z score. Look up the z score on the table to find the probability of getting anything equal to or lesser than the value you chose.

What is the area to the left of z equals 0.25?
It is the description of z as the lower quartile.
How do you find the area to the right of the z-score?
Charts typically show and list the area to the left of the Z-Score value. To find the area to the right, just subtract the Z-Score value from 1; e.g. if the Z-Score value is .75 then take 1-.75 = .25.
How do you find probabilty of negative z score?
Let z be positive so that -z is the negative z score for which you want the probability. Pr(Z < -z) = Pr(Z > z) = 1 - Pr(Z < z).
How do you find a z-score?
Z Score is (x-mu)/sigma. The Z-Score allows you to go to a standard normal distribution chart and to determine probabilities or numerical values.
