# Question 1 # You are working as a data analyst for a private firm, # and receive an email from your supervisor. # "Dear Employee" (You'd think he'd known your name by now) # "I sent you over some data from experiments on the tensile strength of # different steel samples. I need you to determine if there is evidence # that the treated steel has a tensile strength higher than mu=377.9095. # Test it at the usual alpha=5% level." # (Note: Your test should look for the difference between mu_treatment-377.9095.) # This data is saved as "tensileData" mu=377.9095
