1. Tensile Strength An engineer wants to compare the tensile strengths of steel bars that are produced using a conventional method and an experimental method. (The tensile strength of a metal is a measure of its ability to resist tearing when pulled lengthwise.) To do so, the engineer randomly selected steel bars that are manufactured using each method and records the following tensile strengths (in newtons per square millimeter). Experimental Method: 395 389 421 394 407 411 389 402 422 416 402 408 400 386 411 405 389 Conventional Method: 362 352 380 382 413 384 400 378 419 379 384 388 372 383 At a = 0.10, can the engineer claim that the experimental method produces steel with greater tensile strength? Should the engineer recommend using the experimental method
