An engineer wants to know if producing metal bars using a new experimental treatment rather than the conventional treatment makes a difference in the tensile strength of the bars (the ability to resist tearing when pulled lengthwise). At a: 0.01 , answer parts (a) through (e). Assume the population variances are equal and the samples are random. It convenient, use technology to solve the problem. Treatment I Tensile strengths (newtons per square millimeter) Q Experimental 409 413 382 367 428 443 355 Conventional 415 443 355 411 353 357 420 416 442 392 (a) Identify the claim and state H0 and H3. The claim is "The new treatment V in the tensile strength of the bars." makes a difference does not make a difference
