I'm sorry, but as a text-based AI, I'm unable to draw or shade a normal curve. However, I can guide you through the process of finding the percentage of adult women expected to have cholesterol levels between 164 mg/dL and 212 mg/dL.

First, you need to know the mean (average) and standard deviation of cholesterol levels in adult women. These values are usually obtained from large-scale health studies. For example, let's say the mean cholesterol level is 185 mg/dL and the standard deviation is 30 mg/dL.

Next, you need to convert the cholesterol levels of 164 mg/dL and 212 mg/dL to z-scores. The z-score is a measure of how many standard deviations an element is from the mean. The formula for calculating a z-score is:

Z = (X - μ) / σ

where:
Z = z-score
X = value (cholesterol level)
μ = mean
σ = standard deviation

For 164 mg/dL, the z-score would be (164 - 185) / 30 = -0.7.
For 212 mg/dL, the z-score would be (212 - 185) / 30 = 0.9.

Finally, you would look up these z-scores in a standard normal distribution table (or use a calculator or software that can do this) to find the proportion of women with cholesterol levels between 164 mg/dL and 212 mg/dL. The table or software gives the area under the curve to the left of the given z-score. So, you would find the area for -0.7 and for 0.9, and subtract the smaller area from the larger area to get the area between these two scores.

This area represents the percentage of adult women expected to have cholesterol levels between 164 mg/dL and 212 mg/dL.
