“A town has two hospitals. On the average, there are 45 babies delivered each day in the larger hospital. The smaller hospital has about 15 births each day.

In one year each hospital recorded those days in which the number of boys born was 60% or more of the total deliveries for that day in that hospital. Do you think it’s more likely that the larger hospital recorded more such days than the smaller hospital or that the two recorded roughly the same number of such days?” (Merseth, 2003, p. 69).
