Doing homework Refer to Exercise 9.

(a) Make a graph of the population distribution given that there are $3000$ students in the school. (Hint: What type of variable is being measured?)

(b) Sketch a possible graph of the distribution of sample data for the SRS of size $100$ taken by the AP Statistics students.

There are $3000$students in the school.

We also know that $60\%$of the students did all their assigned homework last week.

$60\%\times 3000=1800$

Thus we then know that $1800$students did all their assigned homework last week, while $1200$students did not.

All bars should be the same width and height, and the number of pupils should be the same:

$100$students are in the sample.

We also know that approximately $60\%$of the students did all their assigned homework last week.$60\%\times 100=60$

As a result, we know that around $60$pupils completed all of their given homework last week, whereas approximately$40$ kids did not.

All bars should be the same width and height, and the number of pupils should be the same:

As a result, we know that around 60 pupils completed all of their given homework last week, whereas approximately 40 kids did not.
