Exercise 4. Suppose z, is a list of 733 numbers whose box plot values are . the minimum is 27.3, the lower fourth (first quartile) is 40.8, the median is 49.6, the upper fourth (third quartile) is 58.9, and e maximum is 75.0. Below is a list of assertions. For each decide if it must be true or not. (A) True or False: At least 168 values must be 40.8. (B) True or False: At least 344 values must be 2 49.6. (C) True or False: At least 168 values must be 2 54.25. (D) True or False: Each zi must be 75.0. Oxercise 5.

Solution:-
A) True, In the first quartiles there should be 183.25 values
B) True, In two quartiles there must be 366.5 values.
C) True, In the last quartiles there should be 183.25 values.
