Question

### World Population Growth Modelling

The population of the world was recorded to be 5.28 billion in the year 1990 and 6.07 billion in the year 2000.

#### Task Instructions:

(a) **Finding an Exponential Model:**
- Develop an exponential model to represent the population data given for the years 1990 and 2000.
- Utilize the exponential model to predict the world population for the year 2020.

(b) **Population Prediction:**
- Based on your model, determine the year in which the world population is expected to exceed 10 billion.

**Note:** An exponential model typically takes the form $ P(t) = P_0 e^{rt} $, where:
- $ P(t) $ is the population at time $ t $,
- $ P_0 $ is the initial population,
- $ r $ is the growth rate,
- $ t $ is the time in years,
- $ e $ is the base of the natural logarithm.

Apply this model to solve the tasks outlined above.

Question 16 Suppose that you have downloaded data on the daily share prices for a company for the period from the start of 2020 to the end of 2020 from the website of Yahoo Finance UK. You have also calculated the daily rates of return for the company's shares as (closing price - opening price)/opening price. By using the knowledge that you have gained from descriptive statistics, how can you obtain useful information about the company's share performance in terms of risk and return using a range of alternative indicators? Note that you should give necessary formulas for the technical concepts wherever they may apply.
