- Two different box-filling machines are used to fill cereal . . . - Numerade
Two different box-filling machines are used to fill cereal boxes on the assembly line The critical measurement influenced by these machines is the weight of the product in the machines
- Two different box-filling machines are used to fill cereal . . . - Numerade
Step 1 2 First, we know that the variance of the weight of the product is 20 ounces for both machines Since the sample sizes are 36 each, the variance of the sample means is: Var(X) = Var(X#) = 20 36 = 5 9 Now, we can find the standard deviation of the sample means: SD(X) = SD(X#) = √(5 9) = √(5) 3 According to the Central Limit Theorem, the distribution of the sample means is
