The distribution of body size of mosquitoes (as measured by weight) is known to be log-normal (that is, size is normally distributed if logtransformed). The (untransformed) weights of 11 female and 9 male mosquitoes are given below in milligrams (Lounibos et al. 1995). Do the two sexes weigh the same on average?
