WebAs you can see it lies between 2.706 and 3.841. The corresponding probability is between the 0.10 and 0.05 probability levels. That means that the p-value is above 0.05 (it is actually 0.065). Since a p-value of 0.65 is … WebZ-Score Formula. The Z-Score Calculator uses the following formula: z = (x - μ) / σ. Where: z is the standard score or Z-score,. x is the raw score to be standardized,. μ is the mean of the population,. σ is the standard deviation of the population.. Z-Score Calculation Example. The mean of a dataset is 20 and the standard deviation is 7. WebAug 30, 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859. christopher cartwright addleshaw
