Biostatistics standard deviation
WebThe 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(0.05) and 0.6 + 2(0.05). There is roughly a 95% chance that p-hat falls in the … Webminute and a standard deviation of 3.2 beats per minute. A negative change indicates a decrease in heart rate.
