Explain your reasoning. If the graph appears represent a normal distribution, estimate the mean and standard deviation. ent 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 left. o B. Yes, the graph fulfills the properties of the normal distribution. The mean is approximately and the standard deviation is about (Round to two decimal places as needed) Click to select and enter your answer(s) and then click Check Answer.

Explanation / Answer

5.1.11)

We know that, The graph of normal distribution is symmetric about mean,

But here we observe that the graph is not symmetric, It is negatively skewed( left )

Therefore, The Answer is : (A) No, because the graph is skewed left.
