41. A cereal factory is trying methods of increasing the consistency of their product so that all of their cereal boxes have the same weight (or close to it). Previously all of their cereal boxes had a mean weight of 10oz with a standard deviation of 2oz. In a new sample of 50 boxes it was found that they had a mean weight of 10oz with a standard deviation of 1oz. Which is the appropriate alternative hypothesis if σ1 represents the old standard deviation and σ2 represents the new standard deviation.
Group of answer choices
σ1/σ2 >1
σ1/σ2 = 1
σ1= σ2
