WebFind the standard deviation, s, of sample data summarized in the frecuency distribution table below by using the formula below, where x represents the class midpoint, I represents the class frequerncy, and n represents the fotal number of sample values. Also, compare the computed starkard deviation to the standard deviation obtained from the original … 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(0.01) and 0.6 + 2(0.01). There is roughly a 95% chance that p-hat falls in the …
