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 alphaequals0.10, answer parts (a) through (e). Assume the population variances are equal and the samples are random. If convenient, use technology to solve the problem. font size decreased by 1 Start 3 By 2 Table 1st Row 1st Column Treatment 2nd Column Tensile strengths left parenthesis newtons per square millimeter right parenthesis 2nd Row 1st Column Experimental 2nd Column Start 1 By 10 Matrix 1st Row 1st Column 408 2nd Column 397 3rd Column 440 4st Column 417 5st Column 379 6st Column 442 7st Column 392 8st Column 9st Column 10st Column EndMatrix 3rd Row 1st Column Conventional 2nd Column Start 1 By 10 Matrix 1st Row 1st Column 407 2nd Column 438 3rd Column 388 4st Column 431 5st Column 395 6st Column 449 7st Column 426 8st Column 366 9st Column 354 10st Column 398 EndMatrix EndTable Question content area bottom Part 1 (a) Identify the claim and state Upper H 0 and Upper H Subscript a. The claim is "The new treatment makes a difference in the tensile strength of the bars." Part 2 What are Upper H 0 and Upper H Subscript a? The null hypothesis, Upper H 0, is mu 1 equals mu 2 . The alternative hypothesis, Upper H Subscript a, is mu 1 not equals mu 2 . Part 3 Which hypothesis is the claim? The alternative hypothes
