### Educational Content: Understanding Normal Curves**Task:**Draw a normal curve with a mean (\( \mu \)) of 70 and a standard deviation (\( \sigma \)) of 19. Label the mean and the inflection points on the graph.**Instructions:**Choose the correct graph of the normal curve from the options displayed below.#### Graph Options:- **Option A:** - This graph displays a normal distribution curve with the mean indicated at 70, and the inflection points marked at 51 and 89. - **Option B:** - This graph shows a normal distribution curve with the mean at 89, and the inflection points at 70 and 108.- **Option C:** - This graph illustrates a normal distribution curve where the mean is 51, and the inflection points are 32 and 70.**Key Concept:**The inflection points of a normal curve are located one standard deviation (\( \sigma \)) away from the mean (\( \mu \)). In a perfectly drawn normal distribution, these points mark the transition from concave up to concave down on either side of the mean.**Note:**Visual analysis of these graphs will help determine the correct option where the mean and inflection points match the provided parameters (\( \mu = 70 \), \( \sigma = 19 \)).

Determine whether the graph shown could represent a variable with a normal distribution. Explain your reasoning. If the graph appears to represent a normal distribution, estimate the mean and standard deviation. 32 35 38 41 44 47 50 53 56 E. The graph could represent a variable with a normal distribution because the curve is symmetric and bell-shaped. Its mean is approximately 44, and its standard deviation is approximately 32. (Round to one decimal place as needed.) Q right. O C. The graph could not represent a variable with a normal distribution because the curve has two modes. O D. The graph could not represent a variable with a normal distribution because the curve crosses the x-axis. O F. The graph could not represent a variable with a normal distribution because the graph is skewed to the left. 4
