(a) From the spectral data ( H, C NMR, IR, MS) you were given,
identify the structure of your product. Explain why you chose your
particular product based on the spectroscopic data.
(b) Fully assign the 1H NMR spectrum of your product (i.e.
determine which peaks in the 1H NMR correspond to which hydrogens
in the product). You will not receive full marks for determination
of the unknown unless you assign the 1H NMR spectrum
completely.

Sleep (Raw Data, Software Required): Assume the general population gets an average of 7 hours of sleep per night. You randomly select 35 college students and survey them on the number of hours of sleep they get per night. The data is found in the table below. You claim that college students get less sleep than the general population. That is, you claim the mean number of hours of sleep for all college students is less than 7 hours. Test...
