Step 1 :We are given that women's weights are normally distributed with a mean of \(161.8 \mathrm{lb}\) and a standard deviation of \(43.4 \mathrm{lb}\).
Step 2 :We are asked to find the percentage of women whose weights fall within the range of \(147.3 \mathrm{lb}\) to \(214 \mathrm{lb}\).
Step 3 :To solve this, we can standardize the weights using the z-score formula: \(z = \frac{X - \mu}{\sigma}\), where \(X\) is the value we are standardizing, \(\mu\) is the mean, and \(\sigma\) is the standard deviation.
Step 4 :We calculate two z-scores: one for the lower limit (\(147.3 \mathrm{lb}\)) and one for the upper limit (\(214 \mathrm{lb}\)).
Step 5 :The z-score for the lower limit is \(-0.334\) and for the upper limit is \(1.203\).
Step 6 :We then find the probabilities corresponding to these z-scores using the standard normal distribution. The probability for the lower limit is \(0.369\) and for the upper limit is \(0.885\).
Step 7 :The difference between these probabilities gives us the percentage of women whose weights fall within the given range.
Step 8 :The percentage of women that have weights between those limits is \(\boxed{51.63 \%}\).
