The data modeled by the box plots represent the battery life of two different brands of batteries that were tested.

(a) What is the median value of each data set?

(b) What is the range for each data set?

(c) What is the interquartile range for each data
set?

(d) Which battery would you recommend to a
friend? Explain your choice.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
