Question

Ten voters were picked at random from those who voted in favour of a certain proposition and twelve from those who voted against it. The following figures give their ages:
In favour 28 33 27 31 29 25 50 30 25 41
Against 31 43 49 32 40 41 48 30 29 39 42 36
At 5% percent level of significance, it is evidence from the data that the mean age of those voting against the proposition is significantly different from the mean of those voting for it?
