47 50 53 56 59 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. The graph could not represent a variable with a normal distribution because the curve has two modes. O B. The graph could represent a variable with a normal distribution because the curve is symmetric and bell-shaped. Its mean is approximately and its standard deviation is approximately (Round to one decimal place as needed.) OC. The graph could not represent a variable with a normal distribution because the curve crosses the x-axis O D. The graph could not represent a variable with a normal distribution because the graph is skewed to the left O E. The graph could not represent a variable with a normal distribution because the curve is constant O F. The graph could not represent a variable with a normal distribution because the graph is skewed to the right.
