[OSWALD]

You read that the results of a t-test was t(12) = 3.98, p >.01 . What does this mean?
 
  a. The t value is 12, the degrees of freedom is 3.98, and the result would occur by chance fewer than 1 in 100 times.
  b. The t value is 3.98, the degrees of freedom is 12, and the results would occur by chance fewer than 1 in 100 times.
  c. The t value is .01, the degrees of freedom is 12, and the results would occur by chance fewer than 3.98 in 100 times.
  d. The t value is .01, the degrees of freedom is 3.98, and the results would occur by chance fewer than 12 in 100 times.
