Now, this statement is the exact same thing as the probability that the sampling mean, or the mean of the sample, not the sample mean, the probability of the mean of the sampling distribution is within two standard deviations of the sampling distribution of x is also going to be the same number, is also going to be equal to 95.4%. These are the exact same statement. If x is within two standard deviations of this, then this, then the mean is within two standard deviations of x. These are just two ways of phrasing the same thing. Now, we know that the mean of the sampling distribution is the same thing as the mean of the population distribution, which is the same thing as the parameter p, the proportion of people, or the proportion of the population that is a one. This right here is the same thing as the population mean. This statement right here, we can switch this with p. The probability that p is within two standard deviations of the sampling distribution of x is 95.4%.
