    T is equal 1.4. None of the previous values are correct.

    Explanation:

    t = r * sqrt ((n-2) / (1 - r^2))

    = 0.28 * sqrt (18/0.72)

    = 1.4

    T is simply the calculated difference represented in units of standard error. The greater the magnitude of T, the greater the evidence against the null hypothesis.
