Question
**Understanding Normal Distribution in Birth Weights** **Problem Scenario:** Suppose the birth weights of full-term babies are normally distributed with a mean of 3300 grams and a standard deviation of 500 grams. Complete parts (a) through (c) below. **(a) Draw a normal curve with the parameters labeled. Choose the correct graph below.** - **Options:** - **A:** A normally distributed curve with the mean labeled at X and three points (Q) labeled on each side. - **B:** A normally distributed curve with the mean labeled at X and one point (Q) labeled on each side. - **C:** A normally distributed curve with the mean labeled at X and no points labeled. - **D:** A normally distributed curve with the mean labeled at X and two points (Q) labeled on each side. *Explanation:* In normal distribution, the curve is symmetric about the mean (3300 grams), and the points where the curve changes curvature are related to the standard deviation (500 grams). **(b) Shade the region that represents the proportion of full-term babies who weigh more than 4300 grams. Choose the correct graph below:** - **Options:** - **A:** A normally distributed curve with shading on the left tail starting from X=4300 grams. - **B:** A normally distributed curve with shading on the right tail starting from X=4300 grams. - **C:** A normally distributed curve with shading on the central region between 3300 grams and 4300 grams. - **D:** A normally distributed curve with no shading. *Explanation:* To represent babies weighing more than 4300 grams, the region to the right of X=4300 grams should be shaded, emphasizing the right tail of the normal distribution. **(c) Suppose the area under the normal curve to the right of X = 4300 is 0.0228. Provide an interpretation of this result. 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 [blank] grams. *Explanation:* The given area under the normal curve to the right of X = 4300 grams (0.0228) indicates that only about

**Birth Weight Distribution of Full-term Babies** **Background Information:** Suppose the birth weights of full-term babies are normally distributed with a mean (μ) of 3300 grams and a standard deviation (σ) of 500 grams. Complete parts (a) through (c) below. **Part (a):** The task is to identify which of the provided graphs represents the proportion of full-term babies who weigh less than 2800 grams. - Each graph is a probability density function (bell curve) depicting possible birth weights. - The correct graph should have the area to the left of 2800 grams shaded. **Graphs Explanation:** 1. **Graph A:** Shows a normal distribution with a left-shaded region (area under the curve) correctly starting from the peak and extending leftwards covering up to 2800 grams. 2. **Graph B:** Displays a normal distribution with a left-shaded region but appears to have incorrectly marked regions or different shading pattern. 3. **Graph C:** Incorrect shading for the specified value. 4. **Graph D:** Similar to graph B and does not correctly shade the left region up to 2800 grams. 5. **Graph E:** Incorrect shading for the specified value. 6. **Graph F:** Shows a normal distribution with a left-shaded region correctly from the peak extending leftwards up to 2800 grams BUT could be more visibly correct. **Choose the most accurate shaded graph which correctly represents the calculation.** **Part (b):** Shade the region that depicts the proportion of full-term babies who weigh more than 4300 grams. Choose the correct graph below. - **Graph G:** Correctly shows the shaded region to the right of 4300 grams. - **Graph H:** Shading is incorrect for the specified region. - **Graph I:** Incorrect shading. - **Graph J:** Incorrect shading. **Part (c):** Suppose the area under the normal curve to the right of X = 4300 grams is 0.0228. Provide an interpretation of this result. Select the correct option below and fill in the answer box to complete your choice correctly. 1. **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. 2. **Option B:** The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is
