Question

Aspirin is packed in 120 tab bottles with weight normally distributed with mean 600g and standard deviation 6g.

We want to figure out what is the probabilty that a bottle of aspirin randomly picked from the production batch will weigh between 594g and 606g.

1.Do we have to calculate one z-score or two z-scores?

2.The negative z-score is

3.The positive z-score is

4. The probability that a bottle of aspirin will have weight between 594g and 606g 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.
