The wаste prоduced by а prоcess histоricаlly had an average weight of 3.2 pounds. It is suspected that the aging of the equipment used in the process has affected amount of waste in recent years. Suppose you take a random sample of 36 runs of the process, and you find that the sample mean of their weight of waste is 3.8 pounds, with a sample standard deviation of 0.75 pounds. The standard error of the (sample) mean is [a] pounds. (Round your answer to 3 decimal places.)
