I'm trying to trying to work out the mean average age based on the data from a survey when the ages are ranged. The ages are ranged 16 - 21, 22 - 26, 27 - 32 etc.

So for example 4 respondents where aged between 16-21, 7 between 22-26 and 12 between 27-32.

Does anyone know how to do this? I know how to work out the mean, but how do you do it when the data is presented like this?

Thanks!

Information began to spread one day in a city with a population of 100,000. Within 7 days, 10,000 heard about the information.
Assume that the rate of increase of the number who have heard the rumor is proportional to the number who have not yet heard it. How long will it be until half the population of the city has heard the rumor?
