9 Fig. 9.1 shows box and whisker diagrams which summarise the birth rates per 1000 people for all the countries in three of the regions as given in the pre-release data set.
The diagrams were drawn as part of an investigation comparing birth rates in different regions of the world.

- Discuss the distributions of birth rates in these regions of the world.
Make three different statements. You should refer to both information from the box and whisker diagrams and your knowledge of the large data set.
- The birth rates for all the countries in Australasia are shown below.
| Country | Birth rate per 1000 |
| Australia | 12.19 |
| New Zealand | 13.4 |
| Papua New Guinea | 24.89 |
- Explain why the calculation below is not a correct method for finding the birth rate per 1000 for Australasia as a whole.
$$\frac { 12.19 + 13.4 + 24.89 } { 3 } \approx 16.83$$
- Without doing any calculations, explain whether the birth rate per 1000 for Australasia as a whole is higher or lower than 16.83 .
The scatter diagram in Fig. 9.2 shows birth rate per 1000 and physicians/ 1000 population for all the countries in the pre-release data set.

- Describe the correlation in the scatter diagram.
- Discuss briefly whether the scatter diagram shows that high birth rates would be reduced by increasing the number of physicians in a country.
