For each statistic parameter pair below, calculate the sampling error. Suppose a population has a mean of u = 128, and a random sample of size n = 39 drawn from this population has a sample mean of 137. Determine the sampling error of . Suppose a population has a standard deviation of o = 57, and a random sample of size n = 67 drawn from this population has a sample standard deviation of s = 60. Determine the sampling error of s. Suppose 71% of a population possesses a given characteristic, and 50% of a random sample of size n = 66 drawn from this population possesses the same characteristic. Determine the sampling error of p.
