Part 1

Sketch the region. Choose the correct graph below.

1.43-1.43

A symmetric bell-shaped curve is plotted over a horizontal scale. Two vertical lines run from the scale to the curve and are equidistant from the center and peak of the curve. One vertical line is at the labeled coordinate negative 1.43, which is to the left of the curve's center and peak. The other vertical line is at the labeled coordinate 1.43, which is to the right of the curve's center and peak. The area under the curve between the vertical lines is shaded.

-1.43

A symmetric bell-shaped curve is plotted over a horizontal scale. A vertical line runs from the scale to the curve at labeled coordinate negative 1.43, which is to the left of the curve’s center and peak. The area under the curve to the right of the vertical line is shaded.

-1.43

Your answer is correct.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
