Refer to Exercises 1 and 2, and note that for both exercises the value of n in part (b) is four times what it is in part (a), while p is the same. Use the answers to Exercise 1 or 2 to describe how changing the sample size affects the mean and standard deviation of the distribution of possible sample proportions.
Exercises 1Calculate the mean and the standard deviation of the sampling distribution of possible sample proportions for each combination of sample size (n) and population proportion (p).a. n = 400, p = .5.b. n = 1600, p = .5.
Exercises 2Calculate the mean and the standard deviation of the sampling distribution of possible sample proportions for each combination of sample size (n) and population proportion (p).a. n = 64, p = .8.b. n = 256, p = .8.
