**Educational Content on Normal Distribution of Birth Weights**Suppose the birth weights of full-term babies are normally distributed with a mean of 3500 grams and a standard deviation (σ) of 500 grams. Complete parts (a) through (c) below.---**(a) Draw a normal curve with the parameters labeled. Choose the correct graph below.**Options:1. **A.** Mean = 3500, ends at 45002. **B.** Mean = 2500, ends at 35003. **C.** Mean = 3000, ends at 40004. **D.** Mean = 2500, ends at 4500The correct graph depicts a normal curve centered at 3500 grams and extending to 4500 grams on the horizontal axis, representing the mean.---**(b) Shade the region that represents the proportion of full-term babies who weigh more than 4500 grams. Choose the correct graph below.**Options:1. **A.** Shaded region between 2500 and 35002. **B.** Shaded region between 3000 and 35003. **C.** Shaded region from 3500 to 45004. **D.** Shaded region beyond 4500The correct graph shows the shaded region beyond 4500 grams, representing babies weighing more than this amount.---**(c) Suppose the area under the normal curve to the right of X = 4500 is 0.0228. Provide an interpretation of this result. Select the correct choice below and fill in the answer box to complete your choice.**Options:1. **A.** The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is more than ___ grams.2. **B.** The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is less than ___ grams.For option A, the blank should be filled in with 4500. The correct interpretation is that 0.0228 is the probability that a randomly chosen full-term baby weighs more than 4500 grams.---This content provides an understanding of how normal distribution applies to real-life biological data, such as birth weights, and helps in interpreting statistical probabilities.

One graph in the figure represents a normal distribution with mean u= 15 and standard deviation o = 2. The other graph represents a normal distribution with mean u=11 and standard deviation o = 2. Determine which graph is which and explain how you know. A B 11 15 ... Choose the correct answer below. O A. Graph A has a mean of u = 15 and graph B has a mean of u = 11 because a larger mean shifts the graph to the right. O B. Graph A has a mean of u = 11 and graph B has a mean of u= 15 because a larger mean shifts the graph to the left. O C. Graph A has a mean of u = 11 and graph B has a mean of u = 15 because a larger mean shifts the graph to the right. O D. Graph A has a mean of u = 15 and graph B has a mean of u = 11 because a larger mean shifts the graph to the left.
