This was a quiz question I got wrong:
I just completed Chapt 6 Normal Distributions. I did solving for z value, specfic data, sample mean, standard error, central limit theorem and binomial.
How do I solve this problem. It was not like any demonstration on the video, homework or exercises in the back of each chapt. Could you show me how to do this for future reference? Stacey
If X is a normal random variable with standard deviation 4.00, and if the probability that X is less than 5.52 is .648 (as shown below), then what is the mean of X? (Note: the diagram is not necessarily to scale.)
