each of the following three data sets represents the iq scores of a random sample of adults. iq scores are known to have a mean and median of 100. for each data set, determine the sample standard deviation. then recompute the sample standard deviation assuming that the individual whose iq is 105 is accidentally recorded as 150. for each sample size, state what happens to the standard deviation. comment on the role that the number of observations plays in resistance
