How do you find the area to the right of the z-score?
Charts typically show and list the area to the left of the Z-Score value. To find the area to the right, just subtract the Z-Score value from 1; e.g. if the Z-Score value is .75 then take 1-.75 = .25.
What z-score for the upper 50 percent of area under the normal curve?
A Z-Score of 0 separates the upper 50% of the area from the lower 50% of the area. A Z-Score of 0 is at the mean, median, and mode of the distribution.
What is the z score if 30 percent of the curve lies to the left of the z?
The z-score is 0.84. In the related link, look in the body of the table for .3 area (.2995 closest) and it yields the .84 z-score.
Find the z-score for which 92 percent of the distribution's area lies between -z and z?
z = 1.75
What percent of the area lies to the left of the z-score -1.00?
0.1587 or 15.87%
The area to the left of z is 0.9976 What z-score corresponds to this area?
2.82

What is the z-score for the area equals 0.7704?
In a standard normal distribution curve, one half of the area is .5 (or 50%). 0 is the middle value of the z-score. So, for an area of .7704, z must be negative. Also, the area from 0 to z (which is negative) must be equal to .2704. From the normal probability table, this value is -0.74 Therefore, the z-score for the area equals 0.7704 is -0.74

What is the area above a z-score of 1.28?
It is 0.1003
What percent of the area lies to the left of the z-score -1.00?
0.1587 or 15.87%
Find the z-score that is less than the mean and for which 70 percent of distributions area lies to its right?
It is z = -0.5244
What is the difference between Z-Test and The Z-score?
The Z-score is just the score. The Z-test uses the Z-score to compare to the critical value. That is then used to establish if the null hypothesis is refused.
What is the z score of 0.0011 that corresponds to the area under the standard normal curve?
3.06
Calculate the z-score for a test score of 87 if the mean test score is 81.1 and standrd deviation is 11.06?
z score = (test score - mean score)/SD z score = (87-81.1)/11.06z score = 5.9/11.06z score = .533You can use a z-score chart to calculate the probability from there.
