A sample of 250 observations is selected at random from an infinite population.Given that the population proportion is .25,the standard error of the sampling distribution of the sample proportion is:
A)0.0274
B)0.5000
C)0.0316
D)0.0548

The standard error of the sampling distribution of the sample proportion is calculated using the formula: SE = sqrt[(p(1-p))/n], where p is the population proportion and n is the sample size. Substituting the given values: SE = sqrt[(0.25(1-0.25))/250] = 0.0274.
