WebFor the standard normal distribution, the number of standard deviations above or below the mean is the Z score. The total area under the standard normal distribution curve is 1. Therefore, if we have a Z score, i.e., how far a value is above or below the mean, we can determine the probability of a value less than or greater than that. For example, WebAug 27, 2024 · Let's prove that the area under a standard normal curve (a bell-shaped curve with mean of 0 and standard deviation of 1) is equal to one.Your support is trul...
WebFind the percentage of the area under a normal curve between the mean and the given number of standard deviations from the mean. negative 0.48. The percentage of area under the normal curve between the mean and -0.48 standard deviations from the mean i; The scores on an exam are normally distributed with a mean of 81 and a standard deviation of 7. WebAug 12, 2024 · Method 1: Use z table. To find the area to the right of the z-score, we can simply look up the value 0.25 in the z-table: The represents the area to the left of z = 0.25. Thus, the area to the right is calculated as 1 – 0.5987 = 0.4013. Applied to our scenario, this means approximately 40.13% of students score greater than 87 on this exam.
