The following model was created to show the association between the number of massagesreceived per month and self-predicted stress level: Stress level=10-0.02(number of massages permonth). The coefficient of determination for the model is 0.066 or 6.6%. Choose the true statementregarding this model.

A)The model shows that there is a negative association between stress level and number ofmonthly massages, but the relatively small coefficient of determination suggests that verylittle of the variation is explained by the model, so the model is probably not very good atpredicting stress level.
B)The model shows that on average a person getting no massages will always have a stresslevel of 10.
C)The model shows that getting even one massage a month will decrease your stress level.
D)None of these.

The model indicates a negative association between stress level and massages, but the low coefficient of determination (6.6%) suggests it explains very little of the variation in stress levels, indicating it may not be a strong predictor.
