You are required to calculate the equation for predicting level of prejudice from intelligence level. The same exercise also required that you determine the level of prejudice for someone with an IQ of 115. Relevant statistics are rXY = -.83, sY = 3.651 (using n - 1), and V" for level of prejudice = 22.043.
a. Calculate the standard error of prediction (sw) for the same data.
b. You can be approximately 95% confident that this person's level of prejudice (Y) will fall between which two values?
