Question

The lengths of pregnancies in a small rural village are normally distributed with a mean of 267 days and a standard deviation of 13 days.

 

**Pregnancy Length Analysis in a Rural Village**

The lengths of pregnancies in a small rural village follow a normal distribution, characterized by:

- **Mean:** 267 days
- **Standard Deviation:** 13 days

**Questions for Analysis:**

1. **Range for Middle 95% of Pregnancies:**
   - Determine the range where you would expect to find the middle 95% of pregnancy lengths.
   - Input your range estimates in the form of numbers accurate to one decimal place.
   - **Input Fields:**
     - Between [_____] and [_____].

2. **Range for Middle 95% of Sample Averages:**
   - If samples of size 37 are drawn from the population, identify the range for the middle 95% of sample averages for pregnancy lengths.
   - Again, enter your estimates as numbers with one decimal place of accuracy.
   - **Input Fields:**
     - Between [_____] and [_____].

Ensure your answers are precise and consider standard statistical methods to determine these ranges.
