Question

HELP URGENT 20 PTS!!!! 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 1, 2, and 3 standard deviations from the mean

Answer 1

Explanation:

Draw a generic normal curve. Subdivide the x-axis on each side of the center (mean) into four approx. = parts.

Label the mean with '50.'

1 std. dev. below the mean would be 50-2 = 48;

2 std. dev. would be 48-2= 46, and

3 std dev. would be 46 - 2 = 44

Do the same on the other side of the mean.

The 3 corresponding values will be 52, 54 and 56.
