of 18 {0 complete) it} An engineer wants to know if produdng metal bars using a new expen'mental treatment rather than the conventional treatment makes a dienence 7n the tensie strength of the bars (the ability to resist tearing when pulled lengthwise). At 11:032. answer pans (a) through (e). Assume the population variances are equal and the samples are random. If convenient, use technology to solve the probiem.
