1. This question will ask you to determine the area of a flat piece of metal according to the data in the table below. The answer will need to be correctly state as mean value±?m units, for example Area = 3.2 ± 0.2 cm 2 . Length (cm) Width (cm) 8.4 6.3 8.6 5.9 8.3 6.2 8.7 6.5 8.5 6.3 8.8 6.1 a. (4 points) Determine the mean, standard deviation, and the standard deviation of the mean for the length measurements. Show all your work. Properly report the length and its error. b. (2 points) Determine the mean, standard deviation, and the standard deviation of the mean for the width measurements. Properly report the width and its error.(Hint: you can use scientific calculator or Excel to get results).
