Please I need help as soon as possible

47. C. 30

48. D. 50

49. A. 10

50. A. 10

Step-by-step explanation:

47. The point in the middle of the box is the median, 30

48. The range is the last dot - the first dot outside of the box, 50 - 0 = 50

49. The interquartile range is the range inside the box, the first dot in the box is between 20 and 30, 25. The last dot in the box is between 30 and 40, 35.

35 - 25 = 10

50. Test A's median is 30, Test B's median is 40. 40 - 30 = 10
