(If necessary, consult a list of formulas.) (a) Estimate the number of workers in the sample who are union members by giving the mean of the relevant X distribution (that is, the expectation of the relevant random variable), Do not round your response. (b ) Quantify the uncertainty of your estimate by giving the standard deviation of the distribution. Round your response to at least three decimal places
