Human pregnancy lengths are bell-shaped with a mean of 265 days and a standard deviation of 10 days. Use the Empirical Rule to determine the percent of women whose pregnancies are between 255 and 275 days.
Using the Empirical Rule
1.About 68% of the data lie within 1 standard deviation of the mean.
2.About 95% of the data lie within 2 standard deviations of the mean.
3.About 99.7% of the data lie within 3 standard deviations of the mean.
I am stuck. I am very grateful for you using your spare time to help me out . Thank you in advance.
You can put this solution on YOUR website! Human pregnancy lengths are bell-shaped with a mean of 265 days and a standard deviation of 10 days. Use the Empirical Rule to determine the percent of women whose pregnancies are between 255 and 275 days.
-----------
255 is one standard deviation below 265.
275 is one standard deviation above 265
---
The percentage of a normally distributed population that lies
within one standard deviation of the mean is 68%
Your answer: 68%
