(a) To calculate the percentage increase in population from 1950 to 2014:
Percentage Increase = ((2014 population - 1950 population) / 1950 population) * 100
Percentage Increase = ((7,087,000 - 4,714,900) / 4,714,900) * 100
Percentage Increase = 2,372,100 / 4,714,900 * 100
Percentage Increase = 0.5025 * 100
Percentage Increase = 50.25%
Therefore, the population of Switzerland increased by 50.25% from 1950 to 2014.
(b)
(i) The 1950 population correct to 3 significant figures is 4.71 million.
(ii) The 2014 population in standard form is 7.087 x 10^6.
In 1950, the population of Switzerland was 4 714 900.
In 2014, the population was 7 087 000.
