A psychologist is observing eating behaviour in 131 children aged 33 years old from

Newcastle. He presents each child 2020 new foods which they have never eaten

before. He then records the number of foods they actually try. The results are shown in

the table below.

Number of new foods tried Frequency

0-5 45

6-10 34

11-15 31

16-20 21

Previous research with thousands of children from across the country has shown that

we expect 40% of young children to try 0 to 5 new foods, 30% to try 6 to 10 new

foods, 20% to try 11 to 15 new foods and 10% to try 16 to 20 new foods.

Perform a test to see if the children from Newcastle follow the same distribution that the

research on British children has found.
