Body Weight. Quail chicks, after hatching, can be either stable or unstable depending upon the social environment. The average body weight of a stable chick after 4 weeks is 202.56 grams. The body weight of such chicks has been studied by F. Guibert et al. in the article “Social Instability in Laying Quail: Consequences on Yolk Steroids and Offspring’s Phenotype” (PLOS ONE5(11): e14069. doi:

10.1371/journal.pone.0014069). A hypothesis test is to be performed to decide whether the mean body weight of stable chicks differs from 202.56 grams.
