WebAnswer. For this problem, we know p = 0.43 and n = 50. First, we should check our conditions for the sampling distribution of the sample proportion. n p = 50 ( 0.43) = 21.5 and n ( 1 − p) = 50 ( 1 − 0.43) = 28.5 - both are greater than 5. Since the conditions are satisfied, p ^ will have a sampling distribution that is approximately normal ... WebSpecifically, the confidence level indicates the proportion of confidence intervals, that when constructed given the chosen confidence level over an infinite number of independent trials, will contain the true value of the parameter. For example, if 100 confidence intervals are computed at a 95% confidence level, it is expected that 95 of these ...
