Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 2.4% of the thermometers are rejected because they have readings that are too high and another 2.4% are rejected because they have readings that are too low.

Part 1

Which graph represents the region in which thermometers are rejected? Choose the correct graph below.

A graph with a bell-shaped curve, divided into 3 regions by 2 lines from top to bottom, one near the left edge and one near the right edge. Moving from left to right, the region to the left of the first line is shaded and the region to the right of the second line is shaded.

Your answer is correct.

A graph with a bell-shaped curve, divided into 2 regions by a line from top to bottom on the right side. The region right of the line is shaded.

A graph with a bell-shaped curve, divided into 3 regions by 2 lines from top to bottom, one near the left edge and one near the right edge. The region between the lines is shaded.

A graph with a bell-shaped curve, divided into 2 regions by a line from top to bottom on the left side. The region left of the line is shaded.

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.
