The graphs below are based on government data on unemployment for 2017.

a. which she group has the highest number of people unemployed?

b. which age group has the largest unemployment rate.

c. how are the values in the graphs related.

You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.

The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.

We can deduce that, if x is the number of people between 16 and 19, we have

So, by the relation between the two graphs, we can deduce the total population for each age group.

the expected value of the random variable : 0, 1 and 2
