###### Mherwo Warming and Ice Melt The average depth of the L. Hudson Bay is 305 feet: Climatologists were interested_ in seeing if warming and ice melt were affecting the water level.Fifty-five measurements period of randomly selected weeks yielded a over smple mean of 306.2 feet; The population variance is known to be 3.6. Can it be concluded at the 0.05 level of 'significance that the average depth has increased? Is there evidence of what caused this to happen? Source: World Almanac and Book o
