Hi, Using the normal distribution table, how do you find that probability than z equals a constant? For example, P(z = 1.5). I know how to find the probalility within a range (e.g. 0.5 < z < 1). Thanks

you can't! How would you calculate the probability of a student being an exact height or an exact age to the nearest second?

Hi, Maybe it is an error in the book? Q24c is similar. Regards
What is the answer in the book? I doubt that they would get a basic question incorrect. Are you asking the question right is the query I have.
Hi, I ask the question in: http://www.mathhelpforum.com/math-he...tribution.html Regards
You would get an exact probability in the Binomial and others. Sometimes the Binomial is approximated to the Normal.
