A random sample of size n-58 is taken from a population with mean =-11.5 and standard deviation 0-2 [You may find it useful to reference the z table.] a. Calculate the expected value and the standard error for the sampling distribution of the sample mean. (Negative values should be indicated by a minus sign. Round "expected value" to 1 decimal place and "standard error" to 4 decimal places.) Expected value Standard error -11.5 02626
