A random sample of size n=178 is taken from a population of size N= 3,718 with mean u= -80 and variance o = 190. [You may find it useful to reference the z table.) a-1. Is it necessary to apply the finite population correction factor? O Yes O No a-2. Calculate the expected value and the standard error of the sample mean. (Negative values should be indicated by a minus sign. Round "standard error" to 2 decimal places.) Expected value -80.00 Standard error
