A manufacturer knows that their items have a normally distributed lifespan, with a mean of 13.9 years, and standard deviation of 0.6 years. If you randomly purchase one item, what is the probability it will last longer than 15 years? Round your answer to three decimal places. 2. A particular fruit's weights are normally distributed, with a mean of 734 grams and a standard deviation of 30 grams. If you pick one fruit at random, what is the probability that it will weigh between 646 grams and 791 grams. Round your answer to three decimal places.

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.
