Question:

Problem B: The following dataset is given: 4, 18, 18, 6, 15, 18, 9, 9, 20, 32 (8) Refer to Problem B. Calculate the median and the mode. (1) median = 16.5, and mode = 9 (3) median = 16.5, and mode = = 18 (2) median = 18, and mode = 18 (4) median = 18, and mode = 16.5 (9) Refer to Problem B. Assume that the dataset is a sample, not a population. Calculate the z-score for the value x = 16.5. (1) 3.799 (2) 0.194 (3) 0.375 (4) 0.000 (10) Refer to Problem B. Calculate the lower quartile and the upper quartile. (1) lower quartile = 2.75; upper quartile = 8.25 (2) lower quartile = 7.5; upper quartile = 18 (3) lower quartile = 8.25; upper quartile = 18.5 (4) lower quartile = 9.28; upper quartile = 16.5
