Criminologists have long debated whether there is a relationship between weather and violent crime. The author of the article "Is There a Season for Homicide?" (Criminology, 1988: 287–296) classified 1361 homicides according to season, resulting in the accompanying data.

Winter Spring Summer Fall
328 334 372 327

Does this data suggest that the homicide rate somehow depends on the season? State the relevant hypotheses, then test using α = .05.
