Question

The mid point of a class interval is 42. If the class size is 10 find the upper and lower limits

Answer 1

37 and 47 are the respective lower and upper limit

Answer 2

if we substract (class size÷2) from the mid value of the class interval , then it will be our lower limit . similarly to find upper limit, add (class size ÷2) in the mid value . #be brainly#
