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.
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.
a t test is used inplace of a z-test when the population standard deviation is unknown.
The z-score, for a value z, is the probability that a Standard Normal random variable will have a value greater than z.
z test
You have to beat the developer's time of 126 to get rank S.
Go really slow and end up with one life left

no t test is similar to z test because t test ie used for unknown observation and z is for the medicne
(527-500)/100= Z-score. Then, you should look at the table for this given Z score
You need to look up z-score tables.

That is not a question in The Impossible Test available on the iTunes app store.
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
No
It depends on the population.Use t-test for a small population, N < 30; otherwiase, apply z-test or when N>=30.
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.
