A social psychologist interested in cultural differences compared women of two ethnic groups on a Role Approval Index on which high scores indicated high degrees of approval of one's own social role. The results were as follows.
-If the standard deviation of the distribution of the difference between means is 0.76,what is the t score?
A)(15 - 23)/ 0.76 = -10.53
B)(0.76)(15 - 23)= -6.08
C)[(6.5 + 4.5)/ 2] [0.76] = 4.18
D)(55 - 51)/ 0.76 = 5.26

The t score is calculated by dividing the difference between the means by the standard deviation of the distribution of the difference between means. In this case, the difference between the means is 55 - 51 = 4, and the standard deviation of the distribution of the difference between means is 0.76. Therefore, the t score is 4 / 0.76 = 5.26.
