Suppose you take replicate readings from a spectrophotometer for your sample and you get the following values (i.e., five values obtained from taking a reading of the same standard sample vial a total of 5 times using the same machine and the same settings). Determine how many significant figures should be reported for this single sample (with multiple readings).
