At the tire plant where you work, you are in charge of making sure the tensile strength meets productions standards. You have recently discovered a new recipe for rubber production and want to test the resulting tensile strength of the new recipe compared to the current one to see if the tensile strengths are the same or different. You have taken 5 samples of each recipe and reported the results below.
A) State the Null and Alternative Hypotheses.
B) Is this a left-tailed, right-tailed, or two-tailed test?
C) Run an appropraite t-test (use 5% level of significance); use cell F23 for your output.
