QUESTION 3 Assume that the table below shows the age distribution of nurses in Great Britain in 1851. Make a histogram for the probability distribution. Age range (yr) 20- 29 30- 39 40- 49 50- 59 60- 69 70- 79 80+ Midpoint (x) Percent of nurses 5.6% 9.8% 29.3% 24.9% 19.4% 9.3% 1.7% 54.5 64.575.5 84.5 24.5 34.5 44.5 29,3 % 30% 24.9 % 19.4 20% 9.3% 10% 5.6 % 1.7% 24.5 34.5 44.5 54.5 64.5 74.5 84.5 Age 29.3 % 30% 24.9 % 194 20% 9.8 % 9.3 % 10% 5.6% 1.7% 24.5 34.5 44.5 54.5 64.5 74.5 84.5 Age

Explanation / Answer

Option(C) correctly matches the percentages in the data provided above.

It is also known as the relative frequency diagram, as the frequency in each bin (ie ranges like 0-9, 10-19 etc (which are of equal length)) , are divided by the total frequency and expressed in percentenges so the total is 100%,

If we take the area for each unit rectangles of histogram like for the first one it is 5.6*10=56 , we would get a sum of 1000 which would be the total frequency of nurses involved in this representation.
