A particular gene is expected to be up-regulated in a given experiment. The gene is measured 4 times and a mean expression level of 109 is obtained. It is known from the literature that the standard deviation of the expression level of this gene is 10 and the mean expression level is 100. Can one conclude that the gene is indeed up-regulated?
