A survey is carried out by asking people questions as they come out of a coffee bar.

A section of the questionnaire is shown below.

1. How often do you visit a coffee bar?

GCSE Higher

Jimmy is ordering the t-shirts for the community choir which has 240 members.

He asks a sample of 36 members what colour the t-shirts should be. Each members chooses one colour.

The table shows information about his results.

Colour Number of members
Blue 6
Red 3
Green 7
Yellow 5
Purple 2
Black 6
White 7

(a) Work out how many of the 240 members you think will want black t-shirts.

(b) State any assumption you made and explain how this may affect your answer.


GCSE Higher

Donna is in a class of 25 students, 5 of whom have a pet dog.

There are 2200 students in the school.

(a) Use this information to estimate how many students in the school have pet dogs.


(b) Luka is at a different school.

She is in a class of 28 students, 7 of whom have pet dogs.

Luka and Donna have an idea. They think "In our two classes there are 53 students, 12 of whom have a pet dog. We can use this bigger sample to improve the estimate for Donna's school."

What assumption have they made?

(c) Use this idea to estimate how many students in Donna's school have pet dogs.

If you would like space on the right of the question to write out the solution try this Thinning Feature. It will collapse the text into the left half of your screen but large diagrams will remain unchanged.

The exam-style questions appearing on this site are based on those set in previous examinations (or sample assessment papers for future examinations) by the major examination boards. The wording, diagrams and figures used in these questions have been changed from the originals so that students can have fresh, relevant problem solving practice even if they have previously worked through the related exam paper.

The solutions to the questions on this website are only available to those who have a Transum Subscription.
