Question 1182516
of p(x < 10.7) = .6, then p(x > 10.7) = 1 minus .6 = .4.
this is true.


the reason is that the normal distribution curve is symmetric about the mean.
the area to the left of a score is equal to 1 minus the area to the right of the score.


this can be seen in the following graphs of the normal distribution curve.

in these graphs, i created a mean and a standard deviation that would give me the results of 10.7 having an area to the left of it of .6.


the area to the right of it became .4, which is equal to 1 minus .6.
