What is the z score for a given raw score?
Let your raw score be x and M the mean and S the standard deviation. The Z score for your specific x is Z=(x-M)/S So say your score is 80 (out of 100) and the mean is 70 and the standard deviation is 10. Then the z score for your 80 is: (80-70)/10=1 If on the other hand you got a 60, then the z score would be -1.
What is the z score for a score of 75 if the mean of the distribution is 85 and the standard deviation is the distribution is 5?
z = (75 - 85)/5 = -10/5 = -2
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 z score of area 0.75?
what is the z score for 0.75
What is the minimum score needed to be in the bottom 10 percent of the normal distribution with a mean of 140 and a standard deviation of 55?
To do this, you first need to convert the percentage into a z-score. The bottom 10% yields a z-score of -1.2816. Multiplying this by 55 and adding to the mean gives 69.512. This means all score less that are 69 or less will be in the bottom 10%

What z-score separates the top 10 percent from the rest of the scores?
z = 1.281551
Z-score responding to 10 hours?
The z-score can't be calculated with the information given. A mean & standard deviation is required to put into the formula: Z = (x-mean)/sigma. Your x value is 10.
What is the z score for a score of 75 if the mean of the distribution is 85 and the standard deviation is the distribution is 5?
z = (75 - 85)/5 = -10/5 = -2
How many points is the letter Z worth in scrabble?
The letter Z tile is worth ten (10) points in standard scrabble. Z=10 points. Depending on its position, the 'Z' score can be doubled, re-doubled, tripled or re-tripled and it can also carry the score of the word to which it will be connected.

What is the minimum score needed to be in the bottom 10 percent of the normal distribution with a mean of 140 and a standard deviation of 55?
To do this, you first need to convert the percentage into a z-score. The bottom 10% yields a z-score of -1.2816. Multiplying this by 55 and adding to the mean gives 69.512. This means all score less that are 69 or less will be in the bottom 10%
What is the difference between z-score and t-score?
T-scores and z-scores measure the deviation from normal. The normal for T-score is 50 with standard deviation of 10. if the score on t-score is more than 50, it means that the person scored above normal (average), and vise versa. The normal for Z-score is 0. If Z-score is above 0, then it means that person scored above normal (average), and vise versa.
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.
