The coefficient of correlation is .

Does the relationship between the variables appear to be linear? (Click to select)YesNo


Try squaring the X- variable and then determine the correlation coefficient. ._________

Solutions

Expert Solution

for doing the scatterplot i am using minitab. steps for doing scatterplot:-

copy the data in two column of minitab worksheet and name them "x" and "y" GRAPH SCATTERPLOT double click in SIMPLE "IN Y VARIABLES" select y and " IN X VARIABLES" select x OK.

our scatterplot is:-
