Question

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. 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. a. yes, the graph fulfills the properties of the normal distribution. the mean is approximately □ and the standard deviation is about □. (type whole numbers.) b. no, because the graph is skewed left. c. no, because the graph is skewed right. d. no, because the graph crosses the x - axis.

Explanation:

A normal distribution curve is symmetric about the mean and never crosses the \(x -\)axis. Since the given graph crosses the \(x -\)axis, it does not represent a normal distribution.

Answer:

D. No, because the graph crosses the \(x -\)axis.
