Sampling Error and Standard Error of a Sample

There are 4 samples of 40 individuals each interviewed to find out how often they visit a fast food restaurant in the week. The averages of each sample were 2.5, 3.4, 2.3 and 3.0. If the average is 2.85 and its standard deviationis 50 and we assume that the population is normally distributed.
