If the graph appears to represent a normal distribution, estimate the mean and standard deviation. 5 10 15 20 25 within your choice. A. O B. O c No, because the graph is skewed right. No, because the graph is skewed left. Yes, the graph fulfills the properties of the normal distribution. The mean is approximately Type whole numbers.) and the standard deviation is about O D. No, because the graph crosses the x-axis. 5
