WebNov 28, 2024 · Multiply each value times its respective probability. Each possible outcome represents a portion of the total expected value for the problem or experiment that you are calculating. To find the partial value due to each outcome, multiply the value of the outcome times its probability. [4] 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 ...
