Find the indicated z-score shown in the graph to the right, The z-score is . (Round to two decimal places as needed.) Determine whether the following graph can 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. X TTTTTTTTTTTT 15 20 25 30 Could the graph represent a variable with a normal distribution? Explain your reasoning. Select the correct choice below and, if necessary, fill in the answer boxes within your choice. O A. No, because the graph is skewed right. O B. No, because the graph is skewed left. O C. No, because the graph crosses the x-axis. O D. Yes, the graph fulfills the properties of the normal distribution. The mean is approximately and the standard deviation is about (Type whole numbers.)Find the indicated probability using the standard normal distribution. P(z
