A consumer products company wishes to test at the 0.05 significance level whether its newly reformulated epoxy adhesive is stronger than the existing formulation, which has a mean tensile strength of 439 pounds and a standard deviation of 25 pounds. What is the the power of the test If a random sample of 57 replicates of the new epoxy adhesive is tested under similar conditions, assuming that the mean tensile strength of the new adhesive is 445 pounds? O 0.4336 O 0.4412 O 0.5588 O 0.5664
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
