An automotive manufacturer is testing a new lightweight alloy for vehicle frames. They want to determine if the new alloy (Alloy B) offers significant improvement in tensile strength compared to their current standard alloy (Alloy A).
Engineers conducted tensile strength tests (measured in MPa) on multiple samples of each alloy. They need to determine if Alloy B provides statistically significant improvement in strength compared to Alloy A.
At a significance level of α = 0.05, does Alloy B have a significantly higher mean tensile strength than Alloy A?
Solve this problem and report as a full engineering report. Put all computer code in appendices. Your methodology and analyses should be similar in format to the ones in the sample problems.
