Q 7: If the at risk elderly population in the UK is 55 million then the number (to the nearest thousand) at risk of a fall is (they tell us there were 16 341 cases of fractures and the sample population represents 5% of the at risk population):

1. 27000

2. 10000

3. 40000

4. 50000

5. 60000

The data pertains to the following table.

DJKUMAR,

at first, I'd like to seek clarifications in the above question:

1. The total population of UK is assumed to be 55 million: not the at risk elderly population.

2. I am not sure wherefrom you have taken this question: it has both syntactic and logical errors.

3. Even assuming the 16,341 cases of fractures were observed in a sample of 5% of the total population, then the total population at risk would be,

(5/100)x5,500,000 = 275000

you will have to a another zero to your answer. the at risk population is 55000000.
