Did you know?
WebWe calculated the percentile for z = 0.65 above (74.215%). Using the same method, the percentile for z = 0.40 is 65.540%. Now we subtract the percentiles. 74.215% – 65.540% = 8.675% The probability of an observation having a z-score between 0.40 and 0.65 is 8.675%. WebSubscribe. 10K views 1 year ago z-test.
