Hi
Can I get help in understanding this reply from gemini which I believe contradicts the answer in the 5LB book:
“The third statement (mean of A > mean of B) is true. The mean of a normal curve is the point along the horizontal axis below the “peak” of the curve. The highest point of curve B is
clearly to the right of the highest point of curve A, so the mean of Y is larger
than the mean of X. Notice that the mean has nothing to do with the height of
the normal curve, which only corresponds to how tightly the variable is
gathered around the mean (i.e., how small the standard deviation is)”
Gemini is wrong.
