Question

Consider the following data set: 7, 7, 1, 3, 7, 7, 4, 6, 6, 6, 3, 0. (a) Find the five-number summary and the IQR. Min Q1 Median Q3 Max IQR (b) Calculate x and s (!!Round your standard deviation to three decimal places!!), and the z-score for the smallest and largest observations(!!Round your answers to two decimal places.!!) z-score for smaller observation z = z-score for larger observation z = Is either of these observations unusually large or unusually small? A. Since neither z-score exceeds 2 in absolute value, none of the observations are unusually small or large. B. Since the z-score for the larger observation is larger than 2 in absolute value, the larger value is unusually large. C. Since both z-scores exceed 2 in absolute value, both of the observations are unusual. D. Since the z-score for the smaller observation is larger than 2 in absolute value, the smaller value is unusually small.
