(a) no, the groups are not the same size.
(b) yes, there are close to equal numbers in each group.
(c) no, there are not at least 10 people with weak bones and 10 people with strong bones in each group.
(d) yes, there are at least 10 people with weak bones and 10 people with strong bones in each group
