A random sample of size n = 62 is taken from a population with mean = -11.8 and standard deviation σ 4. [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 b. What is the probability that the sample mean is less than -12? (Round "z" value to 2 decimal places, and final answer to 4 decimal places.) Probability c. What is the probability that the sample mean falls between -12 and -11? (Do not round intermediate calculations. Round "" value to 2 decimal places and final answer to 4 decimal places.) Probability
