The speed at which men versus women mentally rotated an object. Fifteen men and 15 women mentally rotated the object. The men mentally rotated it in 0.0313 s less time than the women. The value of oMi_Mz was 0.01018.
a. What is the best point estimate for the difference in mental rotation speed for the next pair of men and women?
b. In constructing a confidence interval for the expected difference in mental rotation speed between men and women, what difference score will fall in the center of the interval?
c. We can be 99% confident that the true difference in mental rotation speed between men and women is between which two values?
