What is the percent for a quiz score of 14 out of 50?
To find a percentage like this you would take the number you got right and divide by the total number of questions: 14/50. This would come to a .28, then you move the decimal two places to the right to get a whole number, which would come out to 28; 28%.

Find z score for normal distribution for 60th percentile?
it doesn't exist.
How do you find a z score?
If you have a variable X that is normally distributed with mean m and variance s2 then the z-score, Z = (X - m)/s.Z has a standard Normal distribution.
How do you use a z table?
A z table is used to calculate the probability of choosing something that is normally distributed. In order to use it, first a z score is needed. A z score is the number of standard distributions a value is away from the mean of the data. In order to find the z score, take the value of the datum, subtract the mean, then divide by the standard deviation. The result is a z score. Look up the z score on the table to find the probability of getting anything equal to or lesser than the value you chose.
