WebbNote that P(Z ≥ z) = 1 - F(z) (Rule 2). If 1 - F(z) = .05, then F(z) = .95. Looking at Table I in Appx E, F(z) = .95 for z = 1.65 (approximately). Hence, z = 1.65. To find the equivalent x, compute x = (z * 100) + 500 = (1.65 * 100) + 500 = 665. Thus, your GRE score needs to be 665 or higher to qualify for a scholarship. 2. WebbP value from T Score: A t score is basically equivalent to that of the z score having some variation in concept. It also represents the phenomenon of standard deviation.

WebbThe Standard Normal Distribution. If Z ~ N (0, 1), then Z is said to follow a standard normal distribution. P (Z < z) is known as the cumulative distribution function of the random variable Z. For the standard normal distribution, this is usually denoted by F (z). Normally, you would work out the c.d.f. by doing some integration. WebbYou know Φ(a) and you know that the total area under the standard normal curve is 1 so by mathematical deduction: P(Z > a) is: 1 - Φ(a). P(Z > –a) The probability of P(Z > –a) is P(a), which is Φ(a). To understand this we need to appreciate the symmetry of the standard normal distribution curve.
