Is the Z-test the same as Z-scores?
No, the Z-test is not the same as a Z-score. The Z-test is where you take the Z-score and compare it to a critical value to determine if the null hypothesis will be rejected or fail to be rejected.
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 a t-test?
a t test is used inplace of a z-test when the population standard deviation is unknown.
What is measured by the numerator of the z-score test statistic?
The z-score, for a value z, is the probability that a Standard Normal random variable will have a value greater than z.
When are two random samples independent?
z test

A student scored 527 on GRE verbal test what is his percentile rank in a normalized distribution with a mean of 500 and standard deviation of 100?
(527-500)/100= Z-score. Then, you should look at the table for this given Z score
What is the formula to convert a z score into a percentile rank?
You need to look up z-score tables.

What is the difference between t test and z test in hypothesis testing?
It depends on the population.Use t-test for a small population, N < 30; otherwiase, apply z-test or when N>=30.
Is a z test or t test used more often?
t test, because the z test requires knowing the population standard deviation and that's rare. The t test embodies an estimate of the standard deviation.
