QUESTION 5

		There is a 95% chance that the true mean lies in the range 2.72-3.57
		95% of all the countries in the world are likely to have between 2.72 and 3.57 beds per 1000 people
		There is a 95% chance that 3.14 is the actual mean

QUESTION 6

1. Liang et al, Figure 1, panel d shows a correlation coefficient r = -0.24 and P = 0.096. This data demonstrates that there is:

		A significant correlation is detected because P > 0.05
		A significant correlation isNOTdetected because P > 0.05
		A significant correlation is detected becauser is negative
		A significant correlation isNOTdetected because r is negative
		A significant correlation is detected because r < 0.5
