How do you find the number z such that 93 percent of all observations from a standard Normal distribution are greater than z?
The tables for Z-scores are given in the form of P = Prob(Z < z) for various value of P and z. Since Prob(Z > z) = 0.93 > 0.5, then by symmetry, z < 0. So suppose z = -a where a > 0 Now Prob(Z > -a) = 0.93 is the same as Prob(Z < a) = 0.93 [because the standard Normal is symmetric]. therefore, from the tables, a = 1.4758 (approx) and so z = -1.4758 (approx).
What is the value of z if the area between -z and z is 0.777?
To find the value of ( z ) such that the area between (-z) and (z) under the standard normal distribution curve is 0.777, we need to determine the corresponding cumulative probability. The area between (-z) and (z) represents the central portion of the distribution, so we can express this as: ( P(-z < X < z) = 0.777 ). This means that ( P(X < z) - P(X < -z) = 0.777 ). Since the distribution is symmetric, ( P(X < -z) = 1 - P(X < z) ), leading to ( 2P(X < z) - 1 = 0.777 ) or ( P(X < z) = 0.8885 ). Using a standard normal distribution table or calculator, we find that ( z \approx 1.175 ).
What is one-third of z?
z divided by 3
What is the difference of Z and 8?
The difference of Z and 8 is expressed mathematically as Z - 8. This means you subtract 8 from the value of Z. If Z represents a specific number, the result will be that number decreased by 8. If Z is not defined, the expression remains as Z - 8.

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).
What is the translation of a point z to a two units to the right of z?
(z,z+2) or (z+2,z)
What is the greatest common factor of z and z to the second power?
z2 = z * z * 1; z = z * 1. Greatest common factor is z.
