Suppose a population has a mean of μ=131, and a random sample of size n=188 drawn from this population has a sample mean of x¯=127. Determine the sampling error of x¯.
Suppose a population has a standard deviation of σ=75, and a random sample of size n=52 drawn from this population has a sample standard deviation of s=71. Determine the sampling error of s.
Suppose 51% of a population possesses a given characteristic, and 69% of a random sample of size n=175 drawn from this population possesses the same characteristic. Determine the sampling error of p^.
