Proportion from mean and standard deviation
WebbThe Standard Deviation Rule applies: the probability is approximately 0.95 that p-hat falls within 2 standard deviations of the mean, that is, between 0.6 – 2 (0.01) and 0.6 + 2 (0.01). There is roughly a 95% chance that p-hat falls in the … WebbTo calculate "within 1 standard deviation," you need to subtract 1 standard deviation from the mean, then add 1 standard deviation to the mean. That will give you the range for …
