Help! Medal and Fan! :D Which of the following statements are true? I. The area under a normal curve is always equal to 1, no matter what the mean and standard deviation are. II. The smaller the standard deviation of a normal curve is, the higher and narrower the graph. III. Normal curves with different means are centered around different numbers.

    hint: the area under the gaussian or normal curve represents the total probability, and the total probability has to be equal to 1
