Impure cans: A manufacturer of aluminum cans measured the level of impurities in 24 cans. The amounts of impurities, in percent, were as follows. 2.1 1.5 1.9 1.3 2.7 4.9 2.1 1.8 1.3 1.0 3.2 4.4 8.0 4.5 2.5 1.6 2.8 8.2 9.5 3.8 1.9 1.5 2.8 1.6 Construct a boxplot for this sample. Graphical displays should be formatted appropriately. Is it reasonable to treat the sample as coming from an approximately normal population? Explain.
What fraction of the measurements are less than 5.1?
What fraction of the measurements are larger than 3.6?

An aldol condensation reaction was performed where benzaldehyde
and cyclopentanone were used. The product is 2,5
dibenzylidenecyclopentanone or just 2-benzylidenecyclopentanone.
The spectra correspond with the aldehyde being benzaldehyde but the
ketone used could either be acetone, cyclopentanone or cyclohexane.
I need to find the NMR spectra that correspond to cyclopentanone
being the ketone in the aldol condensation. Which NMR spectra
correspond to the correct product?
I think the second set is with cyclohexanone and not
cyclopentanone but I could be...
