From two different machines at an assembly line, let us say A and B, 36 products are taken from each machine as samples and their weights are recorded. Experts in the factory assure that the variance of the weight of product is o² = 1 kg. Besides, µA = µg. Then what is the probability that the sample average kg for machine A is 0.2 larger than or equal to the sample average kg for machine B?

From two different machines at an assembly line, let us say A and B, 36 products are taken from each
machine as samples and their weights are recorded. Experts in the factory assure that the variance of
the weight of product is o? = 1 kg. Besides, HA = MB. Then what is the probability that the sample
average kg for machine A is 0.2 larger than or equal to the sample average kg for machine B?
