### Understanding Normal Distribution in Birth Weights

Suppose the birth weights of full-term babies are normally distributed with a mean (µ) of 3350 grams and a standard deviation (σ) of 485 grams. Below, we explore statistical analysis using this information.

#### Part (a) to (c) Analysis

We have the following normal distribution curves depicting different birth weights and their probabilities:

1. **Diagram Analysis**
   - **First Diagram:** The curve shows a shaded area to the right of \( x = 3835 \) grams.
   - **Second Diagram:** The curve displays a shaded area to the right of \( x = 3350 \) grams.
   - **Third Diagram:** The curve presents a shaded area to the right of \( x = 2865 \) grams.
   - **Fourth Diagram:** The curve indicates a shaded area to the right of \( x = 3835 \) grams and \( x = 4320 \) grams, depicting the tail ends of the distribution.

#### (c) Calculating Probabilities: Interpretation

Suppose the area under the normal curve to the right of \( X = 4320 \) is 0.0228. We need to provide an interpretation of this result:

- **Question for Interpretation:**
  Select the correct choice below and fill in the answer box to complete your choice. *(Type a whole number.)*

  - **Option A:** The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is less than \( \_\_\_\_\_\_ \) grams.
  - **Option B:** The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is more than \( \_\_\_\_\_\_ \) grams.

The answer to this interpretation will help in understanding the distribution of birth weights in full-term babies.

This educational material is designed to enhance your understanding of normal distribution and how it applies in real-life scenarios like birth weights. The diagrams visually represent different areas under the curve, which help in comprehending probability concepts associated with normal distribution.
