(Solution Library) A large supermarket chain is interested in determining whether a difference exists between the mean shelf-life (in days) of Brand S bread

Question: A large supermarket chain is interested in determining whether a difference exists between the mean shelf-life (in days) of Brand S bread and Brand H bread. The results are shown below.

Brand S Brand H
\[\overline{{{x}_{1}}}=4.1\] days \[\overline{{{x}_{2}}}=5.2\] days
\[{{s}_{1}}=1.2\] days \[{{s}_{2}}=1.4\] days
\[{{n}_{1}}=35\] \[{{n}_{2}}=35\]
population mean \[{{\mu }_{1}}\] population mean \[{{\mu }_{2}}\]

Test the claim that there is a difference in the shelf-life of both brands. Decide whether the normal distribution or the t-distribution should be used for this two-sample. Use all three levels of significance \[\alpha =0.10,\alpha =0.05,\alpha =0.01\] . Report the p-value of the test.
