A local weather team is comparing the mean amount of snowfall (in inches) reported by viewers in four different regions of the city. Based on the data, can you conclude that there is a difference between the mean amount of snowfall for these four regions? Use a 0.05 level of significance and assume the population distributions are approximately normal with equal population variances.
