To find the z-score for a particular observation we apply the following formula: Let's take a look at the idea of a z-score within context. For a recent final exam in STAT 500, the mean was 68.55 with a standard deviation of 15.45. If you scored an 80%: Z = ( 80 − 68.55) 15.45 = 0.74, which means your score of 80 was 0.74 SD above the mean ...

Distribution of the Sample Mean
In the previous example we drew a sample of n=16 from a population with μ=20 and σ=5. We found that the probability that the sample mean is greater than 22 is P ( > 22) = 0.0548. Suppose that is unknown and we need to use s to estimate it. We find that s = 4. Then we calculate t, which follows a t-distribution with df = (n-1) = 24.
