A] from the box plots representing the battery brands we shall have the median as follows:
brand x- median is 13
brand y- median is 16

b]  what is range for each data set?
range is given by:
maximum-minimum 
brand x
maximum=16
minimum =11
range=16-11=5
brand y
maximum=18
minimum=10
thus
range=18-10=8
c] what is the interquartile range for each data set?
iqr=[3rd quartile]-[1st quartile]
brand x:
3rd quartile=14.5
1st quartile=12
iqr=14.5-12=2.5
brand y
3rd quartile=17
1st quartile=15
iqr=17-15=2
d] i'd recommend brand y because the average life is greater than brand x. that means it lasts more as compared to the latter
