5. (12 marks) Consider a simple random sample x..X, from the shifted exponential proba- bility density function (Note that taking 0 - 0 gives the probability density function of the exponential distribution.) (a) Givc the likelihood function for 0 and λ in as simplificd of a form as possible. (4 marks) (b) Obtain the maximum likelihood estimators of θ and λ.

The well-known psychologist Dr. Elbod has established what he calls his Generalized Anxiety Scale (GAS). The GAS, which is a scale from 0 to 10, measures the "general anxiety" of an individual, with higher GAS scores corresponding to more anxiety. (Dr. Elbod's assessment of anxiety is based on a variety of measurements, both physiological and psychological.) we're interested in making predictions about individuals' sleep behavior based on their GAS scores. The bivarlate data below give the GAS score (denoted by...

(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.
