Slove this question.
Hi Isha Gupta,
Class limits refers to the upper and lower limit of a class , hence answer (i) 45,49
Class boundaries. They are halfway points that separate the classes.
The lower class boundary of a given class is obtained by averaging the upper limit of the previous class and the lower limit of the given class.
The upper class boundary of a given class is obtained by averaging the upper limit of the class and the lower limit of the next class.
hence answer (ii) 54.5 , 59.5
Class marks. They are the midpoints of the classes.
hence answer (iii) 42
(iv)lower limit - 50, upper limit - 54
(V) size - 4
