I'm needing help with knowing how to get the work to get each standard deviation and then how it would look on the number line

NORMAL DISTRIBUTIONS 2. In an experiment, Mr. Jackson measures the heights of all the students in Math Club. The mean height is 65 inches, the standard deviation is 2 inches, and the heights follow a normal distribution. Part A: Draw the normal curve to represent the distribution of the height data. Label the mean height u, and label each standard deviation: o, 20, and 30. Draw a line at the mean and at each standard deviation. (10 points) 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 Part B: Mr. Jackson randomly selects a student in Math Club. Use the normal
