by Using Normal-Distribution Table Z-scores generally ranges from -3.99 to 0 on the left side and 0 to 3.99 on the right side of the mean. Refer the column & row values for z-score. The point where the row & column meets for the corresponding z-score value is the critical value of Z or the rejection area of one or two tailed z-distribution. For example the -2.95 Z is the left tailed distribution
Contact UsYou can now calculate the z score that corresponds to the bottom portion using NORMSINV(p). You should get z=1.96. Because of symmetry reasons (the standardized normal distribution is symmetric around 0) the z score that corresponds to the upper portion is equal to —z or —1.96
May 30, 2019 · A z-score table shows the percentage of values (usually a decimal figure) to the left of a given z-score on a standard normal distribution. For example, imagine our Z-score value is 1.09. First, look at the left side column of the z-table to find the value corresponding to one decimal place of the z-score (e.g. whole number and the first digit after the decimal point)
Solution: 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 %
Normal distribution is a continuous probability distribution. It is also called Gaussian distribution. The normal distribution density function f (z) is called the Bell Curve because it has the shape that resembles a bell. Standard normal distribution table is used to find the area under the f ( z) function in order to find the probability of a specified range of distribution
A standard normal distribution has a mean of 0 and variance of 1. This is also known as a z distribution. You may see the notation N ( μ, σ 2) where N signifies that the distribution is normal, μ is the mean, and σ 2 is the variance. A Z distribution may be described as N ( 0, 1). Note that since the standard deviation is the square root of the variance then the standard deviation of the standard normal distribution is 1

Simply put, a z score table which is also known as the standard normal table is a table that allows you to know the percentage of values below (to the left) a z score is in a standard normal distribution
Standard Normal Distribution Table. This is the "bell-shaped" curve of the Standard Normal Distribution. It is a Normal Distribution with mean 0 and standard deviation 1. It shows you the percent of population: between 0 and Z (option "0 to Z") less than Z (option "Up to Z") greater than Z (option "Z onwards") It only display values to 0.01%
Therefore: Z score = (700-600) / 150 = 0.67 Now, in order to figure out how well George did on the test we need to determine the percentage of his peers who go higher and lower scores. That’s where z-table (i.e. standard normal distribution table) comes handy. If you noticed there are two z-tables …
A standard normal distribution has a mean of 0 and variance of 1. This is also known as a z distribution. You may see the notation N ( μ, σ 2) where N signifies that the distribution is normal, μ is the mean, and σ 2 is the variance. A Z distribution may be described as N ( 0, 1). Note that since the standard deviation is the square root of the variance then the standard deviation of the standard normal distribution is 1
The Standard Normal Distribution Table. The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z. It does this for positive values of z only (i.e., z-values on the right-hand side of the mean)

This gives you the probability of the area above the Z Score. The complementary cumulative probability and percentile for a 0.551 Z Score is displayed here: 0.290816837282733 = 29.0817% Z Score Table Lookup Here you can submit Z Scores between -3.999 and 3.999 for us to look up in our Normal Distribution Tables
Now using the above table of the standard normal distribution, we have a value for 2.00, which is 0.9772, and now we need to calculate for P (Z >2). We need the right path to the table. Hence, the probability would be 1 – 0.9772, which is equal to 0.0228. Hence 2.28% of the consumers spend above 26000
