WebSolution: The z score for the given data is, z= (85-70)/12=1.25. From the z score table, the fraction of the data within this score is 0.8944. This means 89.44 % of the students are within the test scores of 85 and hence the percentage of students who are above the test scores of 85 = (100-89.44)% = 10.56 %.

The closest area to .7000 is .6984, which is on the row for 0.5 and column for 0.02, making the desired standardized score of \(Z=0.52\).
WebThis is one version of a z table. It gives the probability that a standard normal random variable, Z, will not exceed a given number, z. Equivalently, it gives the probability that any normal random variable will not exceed a value more than a given number of standard deviations above its mean. See Z-score for more information. To look up the probability of … WebThat is, this table reports P(Z ≤ z) = F(z). For a given value of Z, the table reports what proportion of the distribution lies below that value. For example, F(0) = .5; half the area of the standardized normal curve lies to the left of Z = 0. Note that only positive values of Z are reported; as we will see, this is not a
WebApr 7, 2024 · Since the area between 0 and z is .4750, then the area to the left of z = 0.4750 + 0.500 = 0.9750. This is gotten by determining the z score which gives a probability of …
