true or false. Label “T” if it is true, otherwise label “F”.
1-a. If two distributions have the same moment-generating
function, then they are identical at almost all points. For a
random variable X, if its moments of order k (k > 0) exist, then
its moment generating function is continuously differentiable up to
order k.

a. When a molecule has two, degenerate, “infrared active”,
vibrational modes, the two vibrational modes will show absorptions
at different frequencies in the infrared spectrum.

molecules of the substance can cause peak broadening of some of the
absorptions in the infrared spectrum of the...

True or False questions. Determine whether or not each of the
following statements is true. If a statement is true, prove it. If
the statement is false, provide a counterexample and explain how it
constitutes a counterexample. Diagrams can be useful in explaining
such things.
