Scenario: You are the manager of a renowned multivitamin manufacturer. You noticed that customers are particularly curious about the zinc content of your multivitamins after reading an article in a newspaper about the advantages of zinc against viruses. So, you chose to highlight the zinc component of your multivitamins on the label. The zinc content of each tablet is advertised as 5mg and is assumed to be normally distributed with a standard deviation of 0.1mg.

Question: If a random sample of 25 tablets had an average zinc content of 4.98, what would you conclude about the claim's validity that the average zinc content is 5mg?

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.
