A criminologist was interested in whether there was any disparity in sentencing based on the race of the defendant. She selected at random 19 drug convictions for cocaine distribution and compared the prison terms given to the 10 whites and 9 blacks sampled. From performing a hypothesis test to determine if blacks were given longer sentences, what is the absolute value of obtained t score? (Round off to three decimal places if necessary)

Hint: T.INV.2T

Probability: Non-directional or Directional*2 Degrees of freedom: when equal variance: df = n1 + n2 - 2 when unequal variance: df = smaller n - 1 of the two groups

Whites: 3,8,2,7,9,5,5,4,3,2

Blacks: 4,8,7,5,5,7,4,5
