14. A powdered dairy product is produced in two different factories according to the same specications. It is wanted to know if there is any signicant difference between the solubility of the powders produced at the two locations. Solubility data from tests done on samples of products produced from Factory A and Factory B resulted in the following summary statistics: Mean (solubility St. Dev. S.E. Mean metric) (solubility metric m Assume that these samples are representative of all powders produced at these two factories. Is there sufficient evidence to conclude that the mean solubility are different at the two factories? Carry out a hypothesis test
