The Aluminum Association reports that the average American uses 56.8 pounds of aluminum in a year. A random sample of 50 households is monitored for one year to determine aluminum usage. If the population standard deviation of annual usage is 12.3 pounds, what is the probability that the sample mean will be each of the following? a. More than 58...

In the proton NMR for benzil, there are clearly some impurity
peaks below 8 ppm. Although we cannot assign these for certain, is
it possible that these peaks come from unreacted benzoin? Why or
why not?
