Question

Determine whether the graph to the right 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 A No, because the graph crosses the x-axis 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.) C. No, because the graph is skewed right D. No, because the graph skewed left

Explanation / Answer

Ans:Option A is true.(No, as because the graph corrses x -axis)

It can not be a normall distribution cruve or bell curve,as curve crosses the x axis.

Normal distribution curve represent the cummulative probability values,hence it can not cross the x axis.

Normal distribution curve approaches towards x-axis,but dont touch x axis.
