WebOnce this is done, different Z tables can be used to determine various probabilities by finding the probability associated with the Z-score of the value of interest. Below is an example of a cumulative from mean Z table: Reading the Z table for Z = 1.32, the probability that a value lies between a Z-score of 0 and 1.32 is approximately 41%. Web1. What is P (Z ≥ 1.20) Answer: 0.11507. To find out the answer using the above Z-table, we will first look at the corresponding value for the first two digits on the Y axis which is 1.2 and then go to the X axis for find the …
Webgiven directly by our table but we know that P(1 < Z < 0) = 0:5 and from the table P(0 < Z < 0:72) = 0:2642. So, total probability equals to 0.5+0.2642=0.7642. Type 2 What I refer to as Type 2 questions are the problems when you are asked to nd z A rather than probability. In other words, you need to nd a number on the real line rather than the WebAnswer: 0.02024. Example 2: If the raw score is given as 250, the mean is 150 and the standard deviation is 86 then find the value using the z table. Solution: The formula for the z score is given as. z = x−μ σ x − μ σ. x = 250, μ μ = 150 and σ σ = 86. z = 1.16. Using the positive z table the value is 0.8770. Answer: 0.8770.
