    Actual data table :

    X __ y

    2 15

    6 13

    Answer:

    0.953

    Step-by-step explanation:

    The question isnt well formatted :

    The actual data:

    X __ y

    2 15

    6 13

    7 9

    8 8

    12 5

    Using a correlation Coefficient calculator, the correlation Coefficient obtained by fitting the data is 0.953 which depicts a strong linear correlation between the x and y variable. This shows that the value of y increases with a corresponding increase in x values and vice versa.
