Using a graphical method to determine if a set of ungrouped raw data is normally distributed, that data would be normally distributed if:.a. The plot of the data was curvilinear b. The data was randomly distributed
c. The plot of the data was linear
d. The plot of the data was significantly different from zero

c. The plot of the data was linear

Step-by-step explanation:

If a graphical approach is used to analyze a set of raw data group, if the data set is normally distributed it is linear that is it is (attached to each other), we can conclude that the data set is normally distributed because on the plotted graph the information appears linear.

my answer is$ 12

step-by-step explanation:

because 15 -2=12
