The temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 1000 and a standard deviation of 50 0F . If bricks are fired at a temperature above 1124 0F , they will crack and must be disposed of. If the bricks are placed randomly throughout the kiln the proportion of bricks that crack during the firing process is?

Question

The temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 1000 and a standard deviation of 50 ⁰F . If bricks are fired at a temperature above 1124 ⁰F , they will crack and must be disposed of. If the bricks are placed randomly throughout the kiln the proportion of bricks that crack during the firing process is?

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.
