The fifth score in original units is 80. In standard units, this would be -1.4. Standard units are calculated by taking each score and subtracting the mean (69) and then dividing by the standard deviation (10). Therefore, 80 - 69 = 11 and 11 / 10 = 1.1. Finally, 1.1 is multiplied by -1 in order to get -1.4.
