I need help with an NMR question
I need help labeling the IR- spectrum and the H-NMR of
hydrobenzoin. I have included the H-NMR spectrum values if needed.
For the H-nmr I need help on labeling singlets and doublets. For
the IR i need help labeling the peaks.

i got a=0.008 for question a.
i need help for question b
a. Consider the hypothesis testing: H : H = 40, H : H > 40. Assume population standard deviation is o = 5. Take a sample with size 36. The decision making rule is set as: If i < 42, accept Ho; if i > 42, reject H. Based on this decision making rule, find a. b. Consider the hypothesis testing: H: = 40. H: > 40. Assume...

Please help me ! I need this question 5 for the answer and the
proof ! Thank you !
5. Determine the value of the limit 1 - cos(x) M = lim x0 |x| if it exists. Which of the following is true? (a) M = -00 (b) M= 0 (c) M= 1 (d) M= +00 (e) None of the above, or limit does not exist.
i just need help interpreting the IR spectrum and H NMR of
hydrobenzoin. I included the h-nmr spectrum values just in case.
for the H-nmr i need help know if its a singlet or multiplet. thank
you!!
