Which of the statements below are TRUE regarding the mean and standard deviation?
I. As the number of measurements increases, x̄ approaches μ if there is no random error.II. The square of the standard deviation is the average deviation.III. The mean is the center of the Gaussian distribution.IV. The standard deviation measures the width of the Gaussian distribution.
I am supposed to calculate Average absolute deviation (%). I am not sure if 7.16 is the final answer, or do i need to multiply by 100 because they are asking for percent?
