Question
Two independent samples have been selected, 5353 observations from population 1 and 5656 observations from population 2. The sample means have been calculated to be ?⎯⎯⎯1=12.7x¯1=12.7 and ?⎯⎯⎯2=10.7x¯2=10.7. From previous experience with these populations, it is known that the variances are ?21=23σ12=23 and ?22=22σ22=22.
