(a) Find the standard error of the mean for each sampling situation (assuming a normal population). (Round your answers to 2 c places.) Standard Error 8.00 (a) o = 32, n = 4 (b) o = 32, n = 16 (c) o = 32, n = 64 0.02 (b) What happens to the standard error each time you quadruple the sample size? The standard error is reduced by half.

4 n ex You used SS = x (x-x)² when calculating variance and standard deviation. An alternative formula for the standard deviation that is sometimes convenient for hand calculations is shown below. You can find the sample variance by dividing the sum of squares by n-1, and the sample standard deviation by finding the square root of the sample variance. Complete parts (a) and (b) below.
