Final answer:
In each statement, there is a blunder related to the representation of correlation.
Step-by-step explanation:
In each of the given statements, there is a blunder related to the representation of correlation.
a) The statement states that there is a high correlation (r=1.01) between students' attendance and passing rate. However, the correlation coefficient, 'r', ranges from -1 to 1. Therefore, a correlation coefficient greater than 1 is not possible, and this value indicates an error in the calculation.
b) The statement mentions that the correlation between age and income was found to be r=0.67 years. Again, the correlation coefficient cannot be measured in years. It should be represented as a value between -1 and 1.
c) The statement suggests a high correlation between the gender of American workers and their income. However, it does not specify the exact value of the correlation coefficient. This lack of information makes the statement incomplete and ambiguous.
