question 122

Multiple Choice

As a general rule,the normal distribution is used to approximate the sampling distribution of the sample proportion only if:

• A)the sample size n is greater than 30.
• B)the population proportion p is close to 0.50.
• C)the underlying population is normal.
• D)np and n(1 − p)are both greater than or equal to 5.

Proton Spin Decoupled

A technique in NMR spectroscopy where the coupling between protons is removed to simplify the spectrum.

Distinct Quartets

In NMR spectroscopy, a pattern indicating a group of hydrogen atoms coupled to three other hydrogens, resulting in four equally spaced peaks.

Off-Resonance Decoupled

In NMR spectroscopy, a technique used to simplify complex spectra by decoupling specific nuclei from the observed spin-spin interactions.

Proton Spin Decoupled

A technique in nuclear magnetic resonance (NMR) spectroscopy that removes the interaction between proton spins to simplify the spectrum and aid in structural analysis.
