15 POINTS!!

Answer 1

Blue and purple bars will change on the histogram

Explanation:

Size of two bars will change

a) The blue bar with range 65 -70. This bar will reduce in size as three of its reading have shifted to another bar color

b) The purple bar with range 75-80. The size of this bar will increase in size as it will get three new entries from the blue bar
