Extracted text: 7. If you made only n = 1 measurement of rack height, the standard deviation of 41 measurement would be (a) zero, because there is no difference between the value and the average. (b) Equal to the measured value. (c) Undetermined, because you need more measurements to find a standard deviation (d) Infinite because the denominator (n – 1) is zero.
