Answer 1

Answer:

First we have to enter the graph in ascending order:

143cm,145cm,145cm,146cm,146cm,147cm,149cm,150cm,150cm,152cm,152cm,153cm,154cm

Step-by-step explanation:

mean = sum of the terms / number of terms

= 143+145+145+146+146+147+149+150+150+152+152+153+154/13

= 148.6cm

SO THE MEAN HEIGHT IS 148.6Cm

MEDIAN = THE MID HEIGHT

So the mid height = 149cm

Mode =145,146,150,152

Range = maximum-minimum

= 154-143

= 11
