Consider the sampling distribution of the sample proportion of supporters with sample size n - 102. Determine the mean and standard deviation of the sampling distribution of p. Round solutions to four decimal places, if necessary. What is the mean of this distribution? What is the standard error of this distribution?

Furthermore, consider the sampling distribution of a sample proportion with a sample size of n - 141. Use this information to determine the following probabilities. Round solutions to four decimal places, if necessary. Find the probability that in a random sample of 141 observations, greater than 23% of the observations possess the desired characteristic. P(p > 0.23) Find the probability that in a random sample of 141 observations between 18% and 34 of the observations possess the desired characteristic. P(0.18
