Answer 1

Step-by-step explanation:

I'll just tell you how to solve

Make 3 coloums in your notebook naming them as name age and height

Pick any 20 random names and height and give them the height as given in part 2 [ note : neither less than it nor more than it ]

After using it as raw data [ writing in tabular form with names etc ]

Make one more coloum where you write the heights [ given in part 2 ] and the number of people of that group using tally marks .

For histogram take number of people on 'y' axis and height of people on 'x' axis .
