A sample plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. human brain volumes (cm) is given below. Use the given data values to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile 1073 1041 1087 955 1061 1087 1401 1043 List the z scores for the normal quantile plot. (Round to two decimal places as needed. Use ascending order.) Question Viewer Clear all Check answer Help me solve this View an example Get more help -

Use the given data values​ (a sample of female arm circumferences in​ centimeters) to identify the corresponding z scores that are used for a normal quantile​ plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile​ plot, then determine whether the data appear to be from a population with a normal distribution.                           44.2​, 34.5​, 38.2​,  32.7​,  40.9   Part A- List the z scores for the normal quantile plot.     Part B- Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form​ (x,y), where x is the sorted arm circumferences in ascending​ order, and y is the corresponding z score.     Part C- Do the data come from a normally distributed​ population?
