in a standard normal distribution, what proportion of the scores is greater than 2.5? The answer is .0062. Can someone show me how to come up with this answer? Please show your work.
P(z> 2.5)= 1-P(z<2.5)= 1-.9938 =.0062
You can find P(z< 2.5) from normal tables, it is the area under the normal curve corresponding to z=2.5. You may also use excel function NORMS.DIST(2.5,true)
