Sampling Distribution of the Sample Proportion, p-hat

    https://bolt.mph.ufl.edu/6050-6052/module-9/sampling-distribution-of-p-hat/
    The 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 interval (0.5, 0.7) for …
