Question

describe how to sketch a normal curve with a mean of 50 and a standard deviation of 2 indicate how you would label the horizontal axis at one two and three standard deviations from the mean

Answer 1

Answer: See below.

You would sketch a traditional bell curve. For middle line (the highest point of the circle), you would label it with the mead of 50.

Going to the right, you would draw 3 vertical lines. The lines would count up by 2 for each standard deviation.  52, 54, 56

Going to the left, you would draw 3 vertical lines. The lines would count down by 2 for each standard deviation. 48, 46, 44
