WebMay 14, 2024 · In my z table, the statistic t = 1.972 is bracketed by values 1.97 and 1.98 in the margins of the table which cut respective probabilities 0.0244 and 0.0239 from the upper tail of N o r m ( 0, 1). So the approximated p-value is between 0.0239 and 0.0244. Notice that the distributions T ( 24) and N o r m ( 0, 1) are roughly the same, but not ... WebAug 30, 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859.
