We know that the dist is approximately normal, and we have it's mean, and SD. The probability that sample proportion < 0.7 is the tops of all the rectangles below 0.7 summed up for the sampling distribution.
WebbThe standard error may be computed from Equation 6.2.2 using the sample proportions: (6.2.5) S E ≈ 0.47 ( 1 − 0.47) 771 + 0.34 ( 1 − 0.34) 732 = 0.025 For a 90% con dence … WebbThe standard error for the difference between two proportions is symbolized by S E 0. The subscript 0 tells us that this standard error is computed under the null hypothesis ( H 0: p 1 − p 2 = 0 ). Standard Error S E 0 = p ^ ( 1 − p ^) n 1 + p …

WebbThe standard errorof p^{\displaystyle {\hat {p}}}is the square root of this quantity. Because we do not know p(1−p){\displaystyle p(1-p)}, we have to estimate it. Although there are many possible estimators, a conventional one is to use p^{\displaystyle {\hat {p}}}, the sample mean, and plug this into the formula. boy underwear tightWebb29 okt. 2001 · Computing Standard Deviations for Proportions: You already learned about the standard error for the sampling distribution of means, s.e mean = .
