Minimum value in the sample is not smaller than 48 and the maximum value in the sample is not bigger than 73. Therefore there are no probable or possible outliers: mtb > boxp c1. ** * --------i + i--- * * o o o. 8. 0 16. 0 24. 0 32. 0 40. 0 48. 0 (a) sp= (16-8)/10=. 8; median = 16+(5)(. 8)=20 (b) first quartile= 18. 4 (c) third quartile= 22. 4 (d) possible outliers= 8, 8. 8, 10. 4, 28. 8, 30. 4; probable outliers= 35. 2, 40,
